Finite Volume Simulation of Steady Laminer Natural Convection Heat Transfer Through a Mercury –filled Triangular Enclosure with an Isothemal Cold Side Walls and an Isothemal Hot Bottom Wall.

Thermal and flow fields due to laminar steady natural convection in a triangular enclosure having thick conducting sidewalls have been investigated numerically. Inclined left right side walls are maintained at isothermal cold temperatures while the bottom wall is hot temperature. Problem has analyzed non-dimensional governing equations solved using finite volume approach employing more nodes fluid – solid interface. Triangular assumed be filled with mercury as liquid metal Prandtl number of 0.026. Rayleigh varies from 104 106 where thermal computed for various numbers. Consequently, it was observed that stream function temperature contours strongly change high number.The streamline isotherm plots variations average Nusselt inclined also presented. The results explained good agreement another published results.
