A Study of Flow Structures in a Cavity due to Double-Diffusive Natural Convection by Boundary Element Method and Sub-Domain Technique

  • Chapter
Book cover Boundary Elements XIII

Abstract

This paper reports numerical simulation results of natural convection caused by combined heat and mass transfer in a square cavity with insulated top and bottom walls. General time dependent results show the development of velocity, temperature and molar fraction fields. Boundary-domain integral method is used and the sub-domain technique combined with block-solver is employed to reduce computer requirements.
