Numerical solution of the governing equations are obtained using an unconditionally stable numerical scheme consisting of Alternating Direction Implicit (ADI) and Successive Over Relaxation (SOR) methods. The heal transfer rate calculated in terms of the Nusselt number (Nu), is found to be a nonlinear function of hot wall temperature (qh), whereas in fluids with absence of anomalous density the Nusselt number is a linearly increasing function of qh. %8 2002-10-01
