摘要：

A uniform transverse magnetic field is imposed on liquid metal MHD flows. Spatial development of Karman vortex between two insulator walls is numerically simulated. When a strong magnetic field is imposed, MHD diffusion reduces the vortices including three-dimensional component to quasi-two-dimensional ones in downstream. The condition for development of two-dimensional turbulence is discussed.
