Numerical prediction of heat transfer from localized heating in enclosure using cip method

Abstract

In this paper, two-dimensional laminar natural-conv ection heat transfer of air has been numerically solved by Cubic Interpolated Method kno wn as CIP which is based on the Eulerian mesh grid generation. For this investigation a cavi ty has been selected as a geometry which is being heated from bottom of the cavity at three different positions, the sides of the cavity are cold and th e top of the cavity is adiabatic and no heat exchange exist there. The cavity is being heated from three different position of the bottom which is equal in length and equal but in three different position of left, center and right in equally distance. The who le simulation takes place in two various Grasshof number and air has been taken as fluid inside cavit y. Prantl number has been set to 0.7 throughout the simulation. Results are presented in the form of streamlines an d isothermal plots inside the cavity. The results illustrate the heat for middle heated plate is distributed symmetrically through the cavity.
