Mathematical Modeling of Flow in a Granular Permeable Bed Channel
In this research, a two-dimensional mathematical model using turbulence model was developed in a rectangular channel with granular permeable bed. Finite volume method was used for numerical solution of governing equations. The equations considered are discretized using Hybrid difference scheme while applying SIMPLE algorithm to correct velocity components in the continuity equation. In the dev...
متن کاملSinuous flow in metals.
Annealed metals are surprisingly difficult to cut, involving high forces and an unusually thick "chip." This anomaly has long been explained, based on ex situ observations, using a model of smooth plastic flow with uniform shear to describe material removal by chip formation. Here we show that this phenomenon is actually the result of a fundamentally different collective deformation mode--sinuo...
متن کاملNumerical analysis of on the effects of Hydrokinetic turbine presence in flow structure of a compound open-channel
In the recent years, due to the hydropower plants environmental problems, hydrokinetic turbine usages has been increased. Using such turbines in rivers modify natural flow-field. In previous studies, impacts of turbine on the flow-field just only in rectangular open-channel is studied. In this work, the effects of hydrokinetic turbine in a straight compound channel has been numerically studied ...
متن کاملSecondary Currents and Turbulence over a Non-Uniformly Roughened Open-Channel Bed
Large-eddy simulations (LES) of the flow over a non-uniformly roughened channel bed are carried out to study the effect of non-uniform bed roughness on turbulence driven secondary currents and turbulence statistics. The channel bed is comprised of alternating rough and smooth strips, the width of which corresponds to the water depth. The Reynolds number based on hydraulic radius and bulk veloci...
متن کاملThe study of flood flow hydraulic for determining flood bed and river influences points (Atrak River case study)
Measures should be taken to make better use of the rivers in the study, construction and exploitation optimized to contain, mitigate risks and minimize the negative consequences and the improvement of the situation in order to meet human needs and protect the environment there. Route investigated in Khorasan Razavi province and city and river Ghochan is Atrak. Physiographic parameters using dig...
