POSSIBLE TRANSFORMATIONS FOR NATURAL-CONVECTION ON A VERTICAL FLAT-PLATE EMBEDDED IN POROUS-MEDIA WITH PRESCRIBED WALL HEAT-FLUX

This study derived the transformation of boundary layer equations for two-dimensional steady natural convection on a vertical wall embedded in porous media. Three different kinds of thermal boundary conditions are prescribed for wall heat nux:uniform distribution, power law varia tion, and exponential variation. The flow pattern contains three subre gions based on the distance along the flat plate. When inertia resista nce is ignored, similarity solution exists in case wall heat flux is i n linear distribution. The known relationships of uniform wall tempera ture relative to wall heat flux variation and uniform wall heat flux r elative to wall temperature variation in both cases of the pure fluid flow and the pure porous now can all be obtained in the present transf ormation.
