ON MAGNETOHYDRODYNAMIC VERONIS’S THERMOHALINE CONVECTION

In this paper, the mathematically correct solution to more general physical situation such as magnetohydrodynamic Veronis’s [17] thermohaline convection problem for the case of dynamically free, thermally insulating and electrically perfectly conducting boundaries is obtained. Some important results pertaining to the validity of principle of exchange of stabilities has been derived and discussed in detail
