β¦ Synopsis
This paper presents an investigation of the effect of boundary layer on the ionization instability in non-equilibrium MHD plasmas: the Boltzmann transfer equation has been employed in the analysis. It is concluded that the effect of finite boundary layer thickness is to reduce the growth rate. Moreover, the growth rate is not constant across the channel cross-section: it is maximum on the axis and decreases away from the axis. These effects are more pronounced at higher Hall parameters. Further, it is shown that the effect of changing the flow velocit~ of the gas on the growth talc is more important than the effect of changing the wall temperature.

## SUMMARY Effect of ionβslip current on the thermal instability in a boundary layer is studied. The criterion on the position marking the onset of longitudinal vortices is defined in the present paper. The results show that the onset position characterized by the Grashof number depends on the Pran
