Abstract

Two-dimensional steady state mixed convection in a lid-driven parallelogram cavity with isoflux heating from below has been investigated numerically. Two side walls are maintained at constant motion and constant ambient temperature while the upper wall is fixed and kept adiabatic. A uniform constant heat flux is applied at the bottom wall with a view to model heated microchip structure. Governing equations expressing in non-dimensional forms are solved by using Penalty finite element method. Parametric studies are carried out for different values of Richardson number ranges from 0 to 10. The influence of the governing parameters on the Nusselt number at the heat source surface is observed for three different side angles of the moving lids. Results presented in the form of streamline and isotherm plots show a comparative explanation for the variation of heat transfer characteristics.

Keywords
