Abstract
The natural convection from a vertical hot plate with radiation and constant flux is studied numerically to know the velocity and temperature distribution characteristics over a vertical hot plate. The governing equations of the natural convection in two-dimension are solved with the implicit finite difference method, whereas the discretized equations are solved with the iterative relaxation method. The results show that the velocity and the temperature increase along the vertical wall. The influence of the radiation parameter in the boundary layer is significant in increasing the velocity and temperature profiles. The velocity profiles increase with the increase of the radiation parameter. The temperature profiles near the wall plate parallel each other due to the constant heat flux applied to the wall. The influence of the radiation parameter is significant either in velocity or temperature characteristics. At the same time, the effect of the Prandtl number greater than 0.71 is not sensitive to the velocity and temperature variations elsewhere.Keywords
