| Abstract | ||
| This research is focused on the numerical investigation of a steady laminar natural convection heat transfer of liquid (water) with Prandtl number (Pr = 6.2) in a 2-D rectangular enclosure and Rayleigh number, Ra in range from 103 to 105 are taken into consideration for various aspect ratios, AR of 0.5, 1.0 and 2.0. The enclosure object with heated left side wall, while the right side was cold, the top and bottom walls was adiabatic. The theoretical study involved a numerical solution of the Navier-Stokes and energy equations by using finite difference method. The stream function – formulation was used in the mathematical model. The numerical solution is capable of calculating the velocity, stream function, vorticity and temperature fields of the computational domain. A computer program in (FORTRAN 90) was used to carry out the numerical solution and used the Tecplot7 program to draw the results of program. | ||
