Research Abstract

In this study, we attempt to examine characteristics of wall turbulent flows over one-scale and multi-scale rough walls, to simulate effect of free-stream turbulence on these wall turbulences, and to address the understanding of fundamental characteristics of decaying homogeneous-isotropic turbulence, which should be set as free-stream turbulence, by means of numerical simulation, of which accuracy is expected to be higher because of its highly energy-conservation characteristics.
