摘要

Finite-amplitude secondary motions of an electrically conducting fluid between two verticals parallel plates heated differentially in the presence of a horizontal magnetic field are obtained numerically in the limit of a small Prandtl number and a small magnetic Prandtl number. We find that, as in the purely hydrodynamic case with the Hartmann number H=0 examined by nagata and Busse (1983), the bifurcation of the secondary flows is supercritical at the critical Grashof number G=G_c when H is small.
