A Calculation Procedure for Two-Dimensional Elliptic Situations

Abstract A calculation method based on the control-volume approach has been developed for solving two-dimensional elliptic problems involving fluid flow and heat and mass transfer. The main features of the method include a power-law formulation for the combined convection-diffusion Influence, an equation-solving scheme that consists of a block-correction method coupled with a line-by-line procedure, and a new algorithm for handling the interlinkage between the momentum and continuity equations. Although the method is described for steady two-dimensional situations, its extension to unsteady flows and three-dimensional problems is very straightforward.
