A model for "dynamic roughness" in turbulent channel flow


A simple model for roughness elements with a time-varying height was used to investigate the effect of time-dependent, "dynamic" roughness on wall-bounded flow. Temporally varying wall velocities were specified in a turbulent channel flow simulation in order to model the effect of introducing a roughness time scale in addition to a distribution of roughness length scales.
