Reversed Flow Calculations of High Prandtl Number Thermal Boundary Layer Separation
نویسنده
چکیده
A numerical and analytical study of the free convection thermal boundary layer or wall jet at nite Prandtl number is performed to understand the mechanisms of the separation of a high Prandtl number thermal boundary layer ows The model is that adopted by Smith Duck in which the upstream in uence delineates the ow into a double deck structure with the lower deck having thickness O R R being the Rayleigh number The velocities and pressure in the lower deck are obtained thus determining the temperature distribution in the reversed ow zone The asymptotic structure of the ow downstream of separation for the temperature is analysed indicating a functional dependence on the streamfunction in the slowly recirculating inviscid core
