摘要: The purpose of this study was to investigate the influence of surface roughness on turbulent flow across a rotating cylinder. Although smooth rotating cylinders have been extensively investigated, the influence of surface roughness on flow across rotating cylinders has not been reported yet. The parameters for the analysis were chosen such that the Reynolds number is sufficiently large in order to avoid vortex shedding behind the cylinder, while still sufficiently low to maintain the assumption of incompressible flow. Three different Reynolds …
