Experimental investigation of the effects of upstream perturbations in the near-wall and core of a high porosity random-wire porous medium.
… porous medium to investigate the influences of upstream perturbations. The porous medium was fabricated by stacking stainless steel wire-mesh screens in a container of circular cross-section. A step change in porosity is considered a perturbation to the flow as these perturbations would offer an …

Meandering river dynamics
… curvature and bed topology give rise to local perturbations in streamwise fluid velocity, prompting the preferential erosion and sediment deposition that constitute meander behavior. Previous theoretical work has been based on simplified periodic systems. Here we determine the mathematical …
