Application of G.P.D.P. to thermal boundary layer
Abstract
The governing principle of dissipative processes is applied to study the steady state thermal boundary layer along a semi-infinite flat plate when plate temperature differs from that of free stream. The thermal boundary-layer thickness is obtained using a third degree profile. It is found that the rate of heat transfer from the plate to the fluid computed for various Prandtl numbers using present variational method is quite close to the already known exact results. The results of the present investigation are fairly better than those of well-known Karman-Pohlhausen solution.
