Flume Experiment Evaluating Shear Stresses Under Turbulent Flowing Conditions

Shear stresses are produced when a fluid is flowing along a solid boundary layer. Shear stress measurements can be used to evaluate sediment and soil erosion transportation in natural bodies of water, like rivers. With this information, engineers improve

Data concerning the hydrodynamic advantages of arching sea stars modeled in a hydraulics flume.

, 2017
Arched and flat model sea stars were used in a recirculating flow hydraulics flume to assess flow velocities. Methods employed were: using a fluorometer to detect injected rhodamine dye, acoustic Doppler velocimeter to detect mean and shear velocities to

Flow over and around submerged groynes: Numerical modelling and analysis of a groyne flume experiment

, 2019
In submerged conditions groynes add resistance to a river, thereby increasing the water levels for a particular discharge. Groynes are modelled in two ways, either they are included in the bed topography when the grid resolution is sufficiently high or ...

Experimental Study of the Influence of Bank Conditions on Bank Failure and Interaction with Riverbed Deformation During Scouring Process

工程科学与技术, 2017
:Naturally,different bank slope and bank soil compositions can have a combined effect on bank stability and failure.A series of experiments were carried out in a bend flume to study the influence of different bank conditions on bank stability and the ...

Flume Experiment on Step-Pool Mountain Streams

, 2014
階梯-深潭是山區河流常見之地貌，山區河流泥砂級配不均勻，通常階梯由巨石所構成，而深潭中之泥砂則多為沙粒及礫石，在陡坡沖積河床中呈重覆出現的結構；本文經由水槽試驗對階梯-深潭進行定性分析，發現因渠槽邊壁狹窄，限制了水流橫向調整，但水流能對渠床進行沖刷作用呈垂直方向之調整進而發展成階梯-深潭結構，此為消耗水流能量之方式，另外，巨石構成的階梯將會增加形狀阻力也能進而達到水流能量消耗之效果，同時階梯-深潭之結構亦增大水流阻力，使階梯與階梯中的泥砂顆粒不易啟動，達到穩定河床的作用。Steps and pools ...

Transverse bed slope experiments in an annular flume

, 2015
Large scale morphology, in particular bar dimensions and bifurcation dynamics, are greatly affected by the deflection of sediment transport on transverse bed slopes due to gravity and by helical flows. However, existing transverse bed slope predictors are based on a small set of experiments with a minor range of flow conditions and sediment sizes, and ...
