Abstract

A novel approach to model the transient fluid/thermal discharge of a solar storage tanks with an immersed heat exchanger is presented. The model treats the natural convection heat exchanger as a porous medium within the storage fluid. Thus, it is capable of simulating practical heat exchangers comprising many tubes. In the present study, the model is applied to a rectangular storage tank with a 240-tube heat exchanger. Transient temperature distributions and flow streamlines demonstrate the complexity of the flow field and the extent of mixing during discharge.
