Abstract
Inner layer turbulent structures in a high-Re channel flow imposed wall-normal magnetic field were investigated by means of direct numerical simulation (DNS). Due to the magnetic effect, the large scale structure in a high-Re channel flow was suppressed. This degenerated turbulent structure can be characterized by the effective turbulent Reynolds number estimated by a gradient of the Reynolds shear stress. And we found that turbulent structures in this MHD flow has the similarity structures in the non-MHD flow of turbulent Reynolds number corresponded to this effective turbulent Reynolds number.
