Large-Eddy Simulation of Microvortex Generators in a Turbulent Boundary Layer
Heffron, A; Williams, J; Avital, EJ (American Society of Mechanical Engineers, 2021-01-19)The present study investigates the flow physics on MicroVortex Generators (MVGs) in order to improve their performance in turbulent boundary layers (TBLs). TBLs can be a challenging environment for MVGs because of the ... -
A Numerical Study on Suspended Sediment Transport in a Partially Vegetated Channel Flow
Wang, M; Avital, E; Chen, Q; Williams, J; Mi, S; Xie, Q (Elsevier, 2021-03)Turbulent structures generated by vegetation patches play a dominant role in the dispersion of suspended sediment, which in turn is of great significance for ecosystem cycling and river geomorphology development. High ... -
A numerical study on the influence of curvature ratio and vegetation density on a partially vegetated U-bend channel flow
Wang, M; Avital, E; Korakianitis, T; Williams, J; Ai, K (Elsevier, 2020-12-01)Aquatic vegetation dramatically shifts the main flow, secondary flow and turbulent structures in a meandering channel. In this study, hydrodynamics in a bending channel with a vegetation patch (VP) has been numerically ... -
