Buoyancy Effects on Forced Convection Flow and Heat Transfer

Abstract

Buoyancy effects on a forced convection laminar flow with uniform internal heat generation along a vertical flat plate are theoretically studied. Solutions are obtained by means of the integral equation method (the approximate Kármán-Pohlhausen method) and are compared with the solutions obtained by the series expansion method in which the stream function and the temperature function are expanded into power series in terms of the parameter Gr/Re for Pr≧l, whereas in terms of the parameter Gr/(RePr) for Pr<1. Velocity and temperature distributions of fluid are presented for various values of the governing parameters.
