A mathematical model has been developed for determining the dynamic response of a saltstratified solution to heating from below and predictions have been compared with experimental results. All major data trends have been corroborated and good numerical agreement has been obtained for the temperature, salt concentration and thickness of the bottom mixed layer which forms in response to the heating. Underprediction of the time required for thermal effects to penetrate to the top of the solution is attributed to limitations associated with using the energy integral equation to describe conditions in the stable region. Parametric calculations have been performed to determine the effect of bottom heat flux and stabilizing salt gradient on system response.
