The transient flow and heat transfer characteristics of the mixed convection in a horizontal square duct with heated walls are examined numerically in three-dimensional system. The SIMPLE procedure and QUICK scheme are applied to solve the governing equations through a control volume. The working fluid is water, and the temperature dependence of kinetic viscosity v and thermal conductivity λ of water is considered in this analysis. Numerical results show that the reverse flow and the spiral flow flows appear on the upper wall and along the flow direction, respectively. The local Nusselt numbers are presented from the starting point of the heat transfer to the exit corresponding to the transient flow behavior.
