Abstract: The effect of heat and mass transfer on transient laminar free convection flows for saline water over a vertical flat surface is studied. The non-Boussinesq equation to approximate temperature variations with density in buoyancy term is applied. The governing equations are written in their dimensionless form and then solved numerically using an implicit finite difference technique. Two parameters are found to describe the problem; the first one is the density parameter, the second one is the dimensionless Grashof number. Velocity profiles, temperature profiles and Nusselt numbers are discussed.

Keywords: natural convection; mass transfer; saline water; unsteady; vertical plates; flat plates; heat transfer; mass transfer; transient laminar free convection; temperature variations; buoyancy; finite difference method; velocity profiles.
