Abstract: The mixed convection flow and heat transfer in square lid-driven cavities are numerically studied. The top and bottom walls of the cavity are insulated. The top wall of the cavity is moving at a constant speed in its own plane. The various boundary conditions are applied on vertical walls, namely, discrete heating, sinusoidal temperature profiles, partially thermally active walls with uniform temperature and corner heating. The remaining portions on vertical walls of the cavity are insulated when either the discrete heating or the corner heating or the partially thermally active walls is imposed on the vertical wall. The working fluid is considered to be air with the Prandtl number 0.71. The unsteady governing equations together with the initial and boundary conditions are discretized by the finite volume method. The upwind difference scheme and the central difference scheme are considered for the convective terms and the diffusion terms, respectively. A computational code is formulated for the present studies and it is verified against the existing numerical results. It is observed that there is a good agreement between the results of the present code and the existing results. Studies are analyzed over a range of Richardson numbers, heater sizes, heater locations, amplitude ratios, phase deviations, locations of the heating and cooling regions, internal heat generation or absorption and the cavity inclination angles. The results are presented in the form of streamlines, isotherms and velocity profiles. The heat transfer rate is calculated in terms of Nusselt number.
