Two-Dimensional Transient Finite Volume Difusional Approach to Transport Equations

A.S. da CUNHA, W.R. FERREIRA

Abstract


This paper aims at presenting the Diusional Method coupled with the Finite Volume scheme as an alternative approach for solving convection-diusion equations, which under high Peclet numbers may congure a hard numerical task. It is also intended to test the proposed methodology for a case where analytical solution is known and for another one characterized by a high gradient prole. For the last case, results show that false diusion eects are present. Comparisons of the Diusional Method with other numerical schemes are also presented.
