Stability and Newton's law of cooling in double diffusive flow

We study the system of equations for flow of a viscous heat conducting flui d which has dissolved in a salt field. Under the approximation, often emplo yed in the fluid dynamical literature, that the Prandtl number be infinite, we develop a priori bounds and we show the solution depends continuously o n changes in the Newton cooling coefficient.
