Secondary Currents and Turbulence over a Non-Uniformly Roughened Open-Channel Bed

Secondary 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 wh...
