Abstract
Free convection flow of incompressible viscous fluid with dissipation in a rectangular cavity has been studied, a finite difference technique based on ADI scheme is adopted in the solution of the problem. The effect of dissipation parameter (), which usually appears as a term in the energy equation, has been taken into account.The results indicated that the effect of dissipation number () was very small which is accepted with the fact of neglecting the dissipation function in the energy equation of most convection problems.
