Natural convection boundary layer of a radiating gas along a vertical plate

This paper studies the boundary layer development along a vertical porous flat plate maintained at a constant temperature. It is assumed that the temperatures involved are large enough for both convection and radiation effects to be significant. Two problems are analysed. First the asymptotic suction profile valid at large distances from the tip of the plate is discussed. Here an example is given on the dominance of viscous dissipation on natural convection flow fields of large size. Next, the developing boundary layer flow from the tip of the plate is studied. In both cases solutions are effected either by straightforward numerical integration or by asymptotic expansion followed by numerical integration. The temperature characteristic of the flows is discussed quantitatively.
