Abstract : The report presents a physical model to predict the gross flux parameters of steady, turbulent thermohaline natural convection between parallel, horizontal plates. The case treated involves addition of heat and salt at the bottom and removal of both in steady flow at the top of a system without layers of thermoclines. The boundary-layer stability model devised by Louis Howard for thermal natural convection is extended to give the 'thermal-burst' model of thermohaline-boundary-layer stability. A defined density Rayleigh number is used, along with physical reasoning, to give a simple stability criterion for the wall conduction layer. The predicted instability of the wall layer leads to calculations of the Nusselt and Sherwood numbers as well as to such details of the flow structure as temperature and concentration mean profiles and fluctuations.
