Yw. Zhang et A. Faghri, HEAT-TRANSFER ENHANCEMENT IN LATENT-HEAT THERMAL-ENERGY STORAGE-SYSTEM BY USING AN EXTERNAL RADIAL FINNED TUBE, Journal of enhanced heat transfer, 3(2), 1996, pp. 119-127
The heat transfer enhancement in the latent heat thermal energy storag
e system by using an externally finned tube is presented in this paper
. The melting in the phase change materials and heat conduction in the
tube wall and fins are described by a temperature transforming model
coupled to the heat transfer from transfer fluid. The forced convectio
n inside the tube was solved by an analytical method. The results show
that the local Nusselt number inside the tube cannot be simply given
by the Graetz solution. The effects of the tube wall and initial subco
oling on the heat transfer performance are also studied.
