Energy may be extracted from the sensible heat stored in a body of fluid by means of a recirculating flow. A numerical study of the time-dependent, two-dimensional, laminar, convective flow that arises is carried out. The hot fluid is withdrawn at the top and the cold fluid discharged at the bottom of the storage region to preserve the thermal stratification. The nature of the flow is found to be very strongly affected by the buoyancy and the flow configuration. Numerical results are presented over a wide range of governing parameters, that arise from the inflow conditions, flow configuration and the heat transfer mechanisms at the boundaries.
