Abstract

We numerically investigate the influence of two-scale surface roughness on turbulent flow with roughness on one wall. The friction Reynolds number is 400. The two-scale surface roughness influences the rms transverse velocity fluctuation over the smooth wall, which is opposite to the rough wall. The intensity of this fluctuation is a key component in producing the Reynolds stress.
