✦ Synopsis

A ®nite dierence method of solving problems of free convection in a parallel plate channel with or without internal obstructions is presented. It uses the steady-state governing equations including the axial diusion terms, and it does not require pressure matching or conditions to obtain the solution. The buoyancy-induced upward velocity is self-generated without requiring any extra eort or strategy over that normally used for iterative ®nite dierence solution of elliptic equations. The method simply uses the average upward velocity from one iteration to the next until convergence. Comparison and a few illustrations are included to indicate the validity and usefulness of the method.
