Impact of wavy surfaces on particle-laden Poiseuille flow

Abstract
Flow behavior in a rectangular channel changes significantly when one wall has a wavy shape. The presence of small particles enhances velocity fluctuations, which alters the distribution of flow disturbances. This study investigates the influence of wavy walls on both flow and particle movement by simulating four different geometries with surface wavelengths varying from nearly flat to highly wavy. Our results demonstrate that the wavy walls greatly affect particle transport, leading to different deposition patterns over time. By analyzing the Reynolds number associated with the average velocity fluctuations, we gain insights into the influence of wall undulations on flow disturbances and instabilities.
