摘要

The role of temperature dependent viscosity is studied in the flow and vortex instability of a heated horizontal free convection boundary layer flow. Numerical results for the Nusselt, shear stress, critical Grashof, and wave numbers are presented for Prandtl numbers Pr= 0.7, 7, 50, 100, and 500. It is shown that, for liquid heating, variable viscosity effect enhances the heat transfer rate and destabilizes the flow, while for gas heating, the opposite trend is true.
