Abstract
The solidification rate of the latent heat storage units is relatively low and can be significantly improved using fins. The current study investigates the solidification performance of concentric tube-type latent heat storage unit with different designs of herringbone wavy fins. A validated two-dimensional transient solidification heat transfer model for latent heat storage unit with different herringbone wavy fin designs has been utilized and solved in a commercially available CFD solver. For all the studied cases, the fin's volumetric fraction is 5.5 % of the LHSU volume in the numerical solution. Initially, the solidification performance of different herringbone wavy fins and conventional longitudinal fins have comparatively analyzed. The fin-D design has been found to be the most effective, with a 22 % reduction in the solidification time compared to conventional longitudinal fins. Additionally, the effects of geometrical parameters, viz. relative fin height, relative divergence angle, and wave number for fin-D have also been investigated. The optimum values of relative fin height, relative divergence angle and wavenumber have been found at 1, 0.667 and 0.12 mm−1, respectively. The solidification time has been found to be 29 % less for the optimum herringbone wavy fin design than the conventional longitudinal fins.
