Cleaning of simple cohesive soil layers in a radial flow cell
A radial flow cell (RFC, inlet tube radius 0.95 mm and gaps of 1–4.2 mm) was used to investigate the removal of two thin (80–230 µm thick) model soil layers from glass and 304 stainless steel substrates by the flow of water at 20 °C. Under the flow conditions employed (Reynolds numbers 200–1400), inertial effects give rise to recirculation zones and regions of high shear stress on the bottom, soil
