Upper Limits to the Complex Growth Rates in Triply Diffusive Convection

Convective motions can occur in a stably stratified fluid when there are two components contributing to the density which diffuse at different rates. This phenomenon is called double-diffusive convection. To determine the conditions under which these convective motions will occur, the linear stability of two superposed concentration (or one of them may be temperature gradient) gradients has been studied by Stern (1960), Veronis (1965), Nield (1967), Baines and Gill (1969) and Turner (1968) etc.
