河流动力学名词解释

河流动力学名词解释

河流动力学名词解释1. 紊流:液体质点做不规则运动,互相混掺,轨迹曲折混乱的形态叫做紊流。

2. 雷诺数:作用于单位水体的惯性力和粘性力之比组成一个无虽纲数。

3. 级配曲线:通过颗粒分析,求出沙样中各种粒径泥沙的里虽,算出小于各种粒径泥沙的总里虽,然后在半对数坐标纸上,将泥沙粒径D绘于横坐标上,小于该粒径的泥沙在全部沙样中的百分比P 绘于纵坐标上,绘出的D-P关系曲线即为所求的级配曲线。

4. 干容里:指去除水分后的沙样里虽与沙样体积之比。

5. 容里:泥沙颗粒实有里虽与实有体积之比。

6. 等容粒径:体积与泥沙颗粒相等的球体的直径。

7. 筛分粒径:沙粒刚好能通过的与正方形筛孔边长相等的球体直径。

8. 孔隙率:泥沙中孔隙的容积占沙洋总容积的百分比。

9. 比表面积:颗粒表面积与其体积之比。

10. 絮团与絮凝:分散的颗粒相互吸引,聚合成结构疏松、类似棉花团的较大团粒或团块,称为絮团。

而细颗粒泥沙在一定条件下彼此聚合的过程叫做絮凝。

11. 沉速:单颗粒泥沙在无限大静止清水水体中匀速下沉时的速度称为泥沙的沉降速度,简称沉速。

12. 泥沙的水下休止角:在静水中的泥沙,由于摩擦力的作用,可以形成一定的倾斜面而不至塌落,此倾斜面的角度①称为泥沙的水下休止角。

13. 推移质:在河底附近,以滚动、滑动、跳跃形势前进,其速度远小于水流速度的泥沙。

14. 悬移质:悬浮在水中,并在水流方向上与水流以几乎相同的速度前进的泥沙,就是悬移质。

15. 推移质泥沙的分类:①接触质:在运动中始终保持与床面接触的滑动或滚动的泥沙;②跃移质:在床面附近以跳跃形式前进的泥沙;③层移质:河床表面以下成层移动或滚动的泥沙。

16. 床沙(河床质):河床上静止的泥沙。

17. 泥沙的起动:河床上静止的泥沙颗粒(床沙),随着水流条件的增强,到一定条件时开始运动的现象。

18. 泥沙的起动条件:维持泥沙颗粒静止状态的平衡条件遭到破坏,床面泥沙由静止状态转变为运动状态的临界水流条件。

等容粒径(假定球体)D : 算数品均值D : 几何品均值(椭球体)D:泥沙级配曲线(群体性):表示天然泥沙组成特性,在采集的代表沙样中,小于某种粒径的泥沙累计百分数与该粒径在半对数纸上的关系曲线.粒配曲线反映的特性⑴可反映沙样颗粒的大小和范围;⑵可反映沙样组成的均匀程度。

沙样的特征粒径:⑴平均粒径Dm :粒径按其所占重量的百分比为权的加权平均值。

1100n i i m i P d d =∆⋅=∑,max min 2i d d d +=⑵中值粒径50d 表示在全部沙样中,大于和小于这一粒径的泥沙重量刚好相等。

求法:粒配曲线—P=50%天然沙的平均粒径常常大于中值粒径2。

细颗粒泥沙的物理化学特征.细颗粒泥沙在含有电解质的水中,颗粒周围会形成双电层。

通常细颗粒泥沙的主要成分是粘土矿物,它们在含有电解质的水中会发生两种可能:电解质中的离子吸附在泥沙颗粒表面;泥沙颗粒表面的分子发生离解。

不论哪种情况都使泥沙颗粒表面带有负电。

由于凝絮作用,细颗粒在沉积时会连结成絮团,絮团与絮团会连接成集合体,集合体还会搭连而形成网架。

絮凝的新沉积物是一个高度蜂窝状的结构,含水量很高,密度很低,这样的淤积物具有很低的抗剪强度或粘结力。

3。

沉速概念,泥沙沉降状态.单颗粒泥沙在无边界影响的静止清水中的匀速下沉的速度。

因数值主要和粒径有关,也称水力粗度,常用ω表示,单位:cm/s.沉降的形式,泥沙颗粒在静水中下沉时的运动状态与沙粒雷诺数Re d ωνd G ==沙粒性力水流粘Z 力(式中和d 、ω分别为泥沙的粒径及沉速,ν为水的运动粘滞性系数)①层流状态下降:Re d <0。

5,颗粒基本沿垂线下沉,颗粒不发生摆动、转动、滚动,周围水体不发生紊乱现象。

颗粒沉降属于层流状态,下降速度较慢,绕流阻力以摩擦阻力为主,压差阻力相对较小,d C 与Re d 呈直线关系②紊流状态下降:Re d >1000, 泥沙颗粒脱离铅垂线,以极大的紊动状态左摇右摆下沉,附近的水体产生强烈的绕动和涡动。

水力学、水动力学、水文学

水力学、水动力学、水文学

水力学、水动力学、水文学英文回答:Hydraulics, hydrodynamics, and hydrology are three branches of study that are closely related to water. Although they all deal with water, they focus on different aspects and have distinct applications.Hydraulics is the study of the behavior of fluids, particularly in relation to engineering applications. It involves the study of how fluids, such as water, flow through pipes, channels, and other structures. Hydraulics is used in various fields, including civil engineering, mechanical engineering, and environmental engineering. For example, when designing a water supply system for a city, hydraulics is used to determine the flow rate, pressure, and size of pipes needed to deliver water to different locations.Hydrodynamics, on the other hand, is the study of themotion of fluids, including both liquids and gases. It focuses on understanding the forces and movements of fluids in motion. Hydrodynamics is used in fields such as naval architecture, aerospace engineering, and oceanography. For instance, when designing a ship, hydrodynamics is used to analyze the flow of water around the hull and optimize its shape to reduce drag and improve efficiency.Hydrology, as the name suggests, is the study of water in its natural state, including its distribution, movement, and properties on the Earth's surface. It involves analyzing the water cycle, rainfall patterns, river flow, groundwater, and water quality. Hydrology is essential for managing water resources, predicting floods, and assessing the impact of human activities on water systems. For example, hydrology is used to determine the water availability in a watershed and develop strategies for sustainable water management.中文回答:水力学、水动力学和水文学是与水密切相关的三个研究领域。

英文河流动力学水力学Lecture12- Non-Newtonian

CVG5162 – Advanced River HydraulicsLecture 12: Non-Newtonian Fluid Flows Viscosity Recall Dynamic (Absolute) Viscosity ( ) is a measure of the resistance of a fluid to shear stress. In liquids, the viscosity is due to cohesion between molecules. Less viscous fluids flow easier: ketchup is more viscous than water. Newton’s law of viscosity is: dy duµτ= i.e. dydu τµ=where is shear stress (N/m 2) and du/dy is the gradient of velocity in the vertical direction. In fluids, du/dy represents the strain in the fluid, thus this relation is analogous to Young’s modulus [εσE = ]. The classical experiment (performed by Newton) is to place two plates parallel to each other and separated by a distance Y with a fluid in the space between. A tangential force is applied to the top plate (from which is calculated, =F/A), which causes the upper plate to move with velocity U, which is recorded. Figure 1. Source: Daugherty et al.With the no-slip assumption, the fluid particles next to each plate will assume the velocity of the plate. For laminar steady flow, the velocity gradient in the fluid between the plates will be linear.(i.e. du/dy is constant).Fluids for which does not depend on du/dy are described as Newtonian. Most common fluids are Newtonian. However, particularly relevant for some geophysical flows, fluids with very high suspended sediment concentration can be non-Newtonian. If one assumes that a fluid has zero viscosity (and therefore zero friction), the fluid is termed an ideal fluid. Note that an ideal fluid will not undergo strain due to the applied stress, thus it would maintain zero velocity between the two plates.Figure 2. Source: Daugherty et al.Viscosity of a fluid decreases with temperature, because cohesion diminishes. The dynamic viscosity of water at 20ºC is 1.005E-3 N s/m 2. Kinematic Viscosity ( ) is the dynamic viscosity divided by density: ρµν=. The kinematic viscosity of water at 20ºC is 1.007E-6 m 2/s. Turbulent eddy viscosity We have also seen that turbulence adds an extra apparent (eddy) viscosity (νT ), which is due to the increased transfer of momentum between fluid layers as a result of the turbulent motion (i.e. the Reynolds stress): ()dy du uv dy du T νννρτ+=−= Non-Newtonian Fluid We can see from Figure 2 above, that a Non-Newtonian fluid does not have a linear relation between shear stress and strain. In other words, the viscosity coefficient µ is not a constant – it varies with the shear stress applied. Some non-Newtonian fluids are relatively straight-forward, in that the instantaneous shear depends only on du/dy (as in the figure above). These are described as ‘time independent’, ‘purely viscous’, ‘inelastic’, or ‘generalized Newtonian fluids’ (GNF) (Chabbra and Richardson 1999, p.5). In more complex time-dependent non-Newtonian fluids the instantaneous apparent viscosity also depends on the flow history and previous shear rate.An important distinction between types of time-independent non-Newtonian fluids is whether or not they display a yield strength (i.e. whether a threshold stress is required to initiate strain (deformation) of the fluid, i.e. the stress required to get the fluid moving). See Figure 3. Note that the field of rheology bridges non-Newtonian fluids, plastic solids, and soils. Typically, the viscosity of a time-independent non-Newtonian fluid is specified as a function that depends on du/dy. Secondly, a yield stress term may be included. A viscoplastic is a fluid that displays a yield stress. A Bingham-plastic is a viscoplastic with a linear relation between shear and strain once yield shear is obtained:+=dy du y ηττ where τy is the yield stress (the stress required to initiate strain), and η is the dynamic viscosity (the slope of the line after the yield stress). A shear-thinning or pseudo-plastic fluid has no yield stress, but a relatively high viscosity at low strain. A shear-thickening or dilatant fluid has no yield stress, but a relatively low viscosity at low strain (high viscosity at high strain).Figure 3. Source: Chhabra and Richardson 1999. Note that pseudo-plastic fluid and shear-thinning fluid are synonomous. Figure 1.5 applies to polymer solutions, but shows how apparent viscosity decreases with increasing strain rate for a pseuodplastic fluid.Water-Sediment Mixtures The behaviour of fluids with high suspended sediment volumetric concentration (C s ) encompasses the range from Newtonian, to pseudo-plastic, to Bingham plastic, to yield-pseudoplastic depending on sediment concentration. Furthermore, individual clays have different electrochemical properties, and therefore different rheology. The analysis of high C s flows is thus complex. Julien and Lan (1991) provided a succinct summary of research until that time. Bagnold (1954) initiated this research field, and proposed that at high C s , fluid shear would be dominated by interparticle friction and collisions. He found that under very high rates of shear (i.e. high du/dy) and high C s , the shear stress increases as a second power of du/dy. Thus, the fluid can be described as a yield-pseudo plastic with convexivity to the shear stress (see Figure 4). The increased particle interactions at higher du/dy results in increased apparent viscosity (i.e. shear thickening). An empirical power-law equation (Herschel and Bulkley 1926) can be used for the shear in high clay-water suspensions at high du/dy (Govier and Aziz 1987, cited in O’Brien and Julien 1988):n y dy du a +=ττNote that n=2 based on the Bagnold observations. Alternatively, O’Brien and Julien (1988) found that under lower du/dy, the shear stress varies linearly with du/dy, thus at low du/dy the fluid mixture can be described as a Bingham plastic. They also argued that these are more realistic shear rates (du/dy) for geophysical flows. Note that both the yield stress and the dynamic viscosity increase exponentially with sediment concentration – three orders or magnitude increase between C s = 0.1 and 0.4 (O’Brien and Julien 1988)Julien and Lan provide the following summary plots: Figure 4. Source: Julien and Lan (1991)Figure 5. Source: Julien and Lan (1991)O’Brien and Julien (1985), cited in Julien and Lan (1991), proposed the following:2 ++=dy du dy du y ζηττwhere the first term is for the yield stress, the second for viscous (dynamic) stress, and the third term for the ‘turbulent-dispersive’ stress, which accounts for both turbulence and particle-particle interactions, both of which are presumed to vary as a second power with du/dy.Note that 2212s s d a l λρρζ+=, where ρ and l are mixture density and mixing length, a 1 is Bagnold’s empirical constant, λ varies with sediment concentration, and ρs and d s are sediment density and grain size. Note that the first term works out to be the turbulent Reynolds stress, and the second term is Bagnold’s stress due to particle interactions.Julien and Lan (1991) non-dimensionalized their model (see paper) to collapse the various data sets:Figure 6. Source: Julien and Lan (1991)TemperatureCoussot and Piau (1994) found little change in mud suspension rheological behaviour for temperatures ranging from 0°C to 20°C.Thixotropic Non-Newtonian FluidChanson (2006) presented a model for 1D dam-break flow of a high C s thixotropic fluid. A thixotropic fluid is a solid gel-like substance when at rest, but liquefies when agitated. The precise definition of thixotropy is a fluid which undergoes a decreasing apparent viscosity (i.e. reduced shear stress) when exposed to a constant rate of shear (i.e. du/dy) (Chhabra and Richardson 1999). Thus, viscosity is time-dependent. Mud suspensions tend to display thixotropy (Figure 7).Figure 7. Source: Chhabra and Richardson (1999)Chanson utilized a model by Coussot et al. (2002) for the viscosity of a thixotropic fluid:()n o a λµµ+×= whereλαθλ×∂∂×−=∂∂yV t 1 and the four terms µo , n, θ, and α are constants for a given fluid. Note that the viscosity in this model is time dependent. In general , numerical modelling of non-Newtonian fluids involves defining a relation that describes the viscosity of the fluid as a function of the fluid properties and flow (particularly du/dy). This equation must then be included in the set of equations to be solved. References Chanson, H., Jarny, S., and Coussot, P. (2006). "Dam break wave of thixotropic fluid." J.

河流水力学中的水流动力学与水动力学模型

河流水力学中的水流动力学与水动力学模型

河流水力学中的水流动力学与水动力学模型河流水力学是研究河流中水的运动、变化和影响的学科。

水流动力学(Hydrodynamics)和水动力学 (Hydraulics) 是河流水力学中的两个重要分支。

水流动力学主要研究液体无限接近于静止状态而而不是由于静水压力而流动时的力学性质和变化规律。

它包括流体静力学、流体动力学和流体水动力学等内容。

水动力学附着于水文学的领域中,探讨流量与河床之间的互动问题,是应用力学在水文学的一个分支。

在水流动力学的研究中,常用雷诺数来描述流体的流动状态。

雷诺数(Re)是流场中惯性力与粘性力的比值,即Re=惯性力/粘性力,通俗点说,就是比较“快”和比较“慢”两种液体在运动时,惯性力和摩擦力占的比例。

雷诺数越大,惯性力越强,粘性力越弱,流体的速度分布、流线轮廓会发生很大的变化,出现旋力、涡旋、湍流等等。

水流动力学通常研究的对象是静止水体中的水流,比如飞机飞过湖面,水面随之波动形成涟漪、浪花、气泡等图案。

水流动力学的研究不仅和地球上的河流、湖泊、海洋等水域有关,同样应用在航空飞行、化工加工、水电利用、环境污染、生态保护等领域。

而水动力学则是将力学原理用于研究水在管道、水库、持滞池、水闸等设施中的流动规律和相应的物理量时进行研究。

水力学主要通过建立水动力学模型来进行研究,大多数研究通过物理实验来模拟实际情况,得到相关数据进行计算分析。

这些实验中一般会建立两种模型,即放大模型和原型模型。

放大模型将大型水力结构物缩小成比例减小的模型进行配制,以模拟实际工程中的设计。

原型模型则是尽可能地模拟实际情况所建立的模型,往往使用原材料制成,并实际测量水流运动的各种参数。

这种方法一般用于大型水利工程的实验验证,如水坝、堤防等大型设施。

通过对这些模型的实验数据进行计算处理,水动力学研究人员可以对水流动的各项参数进行分析,包括速度、流量、压力、粘度等。

水流动力学和水动力学模型的运用带来了很多好处。

比如,在水力学建模中,通常需要加入其他一些因素,比如气候和水文变化。
