Substantial advances have been made in order to simulate the coupling between a latent thermal energy storage device and a solar collector.
Likewise,approach a numerical for coupling a 2D geometry of a TES system (namely, the cross section of the accumulator) with a solar collector have been developed. This will allow for ultra-fast simulations. Discussions on the applicability of the 2D simplification are also included.
