Double-diffusive buoyancy induced flow in a triangular cavity with corrugated bottom wall: effects of geometrical parameters

A numerical study has been carried out to present flow field, temperature and concentration distribution in a triangular enclosed space with corrugated base surface using finite element method. The cavity consists of an absorber plate and two inclined glass covers. At the base corrugated wall high c...
