Composition and temperature induced natural convection within an open topped vertical circular enclosure has been numerically investigated. A theoretical model that describes the mass, heat and momentum transport processes in a 2-dimensional axisymmetric domain is presented. The model included consideration of the transient development of natural convection flow, density and thermophysical property variations. The results presented are for a n-Pentane liquid vapor diffusing into Air. A description of the transient temperature and concentration gradients development is given along with their effects on the flow field progression.
