... the flow locally and thereby increasing heat transfer. The goal of this study is to investigate the geometry of the shroud in optimizing heat transfer by locally increasing the velocity near the surface of the heat exchanger. Two-dimensional transient simulations are conducted. The immersed heat exchanger...

... is to direct and increase the local velocity across the heat exchanger. The discharge process is numerically simulated for 10 5  < Ra D  < 10 7 and Pr = 3. The immersed heat exchanger is modeled as a two-dimensional isothermal cylinder situated near the top of a store with adiabatic walls. Nusselt...

... in thermal stores using an immersed heat exchanger. The preferred geometry is a low-conductivity baffle of width equal to the effective width of the heat exchanger and 15 or more cylinder diameters in length to ensure nearly fully developed flow at the baffle outlet. confined flow flow simulation heat...
