Equations have been written, and a computational scheme developed, for predicting flow fields and heat transfer phenomena associated with asymmetric gas-driven flows in systems of cylindrical geometry. Cases considered include axisymmetric gas injection wherein the gas-liquid plume is either of constant radius, or expands in a cone-like manner towards the surface. It is, thereby, shown that the model compares reliably with existing axisymmetric computations. Non-central gas flows are then considered and resulting 3-D liquid flow patterns computed. Finally, the temperature fields in an initially stagnant and thermally stratified liquid resulting from the local introduction of gas on the bottom surface is illustrated
