N2 - This article presents a numerical simulation of the transient thermal convection phenomenon in a horizontal circular enclosure containing two immiscible fluids. To cope with the rather complex computational domain encountered when the volume ratio of the two fluids in the enclosure is not unity, a simple radial coordinate transformation technique is used to map the respective domains occupied by the fluids into half-circular ones. Numerical simulation by a finite-difference method is performed for air-water layers as the two-fluid system in the enclosure. The simulated fluid flow structure and temperature distributions are presented by means of contour maps of streamlines and isotherms.
