Abstract
The steady state of combined thermal and mass transport by convection-diffusion in a square lid-driven cavity is studied. The fluid flow is solved by using the vorticity-stream function formulation and transport of temperature and mass are solved by an advection-diffusion equation. The set of governing equations are solved numerically by a second-order finite difference scheme in time and space in a regular grid. The flow, heat and mass transfer are examined in the domain of the Reynolds (Re), Schimidt (Sc), Richardson (Ri), Lewis (Le) dimensionless numbers and the buoyancy ratio parameter (N), covering a wide range of applications. Results shown that Grasolf and Reynolds numbers play an important role in the mass and energy transport either enhancing or retarding this process and the intensification of heat transfer occur when Gr/Re≪1. Comparisons with former investigations are performed and the results shown good agreement.
