The stability of a flow in a side-heated vertical layer with internal heat sources

The linear stability of a combined convective flow in a side-heated plane vertical layer of incompressible fluid is considered. The layer contains uniformly distributed heat sources. The steadystate flow is a superposition of the Gershuni convective flow and a flow induced by the action of the internal heat sources. The stability maps of the combined flow are constructed for different values of the Prandtl number. It is found that the internal sources damp the action of the mechanisms of the Gershuni flow crisis. The lateral heating may result in both the stabilization and the destabilization of the flow caused by the action of internal heat sources.
