This work designs a fractal latent heat storage (LHS) unit with tree-shaped fins for enhancing heat exchange efficiency. The melting/solidification processes inside a fractal LHS unit are experimentally studied by visualization observation, focusing on the role of inclination angles. Heat-transfer characteristics of a latent heat thermal Effects of the configuration of a finned tube on the heat transfer characteristics of a latent heat thermal energy storage (LHTES) unit have been studied experimentally and theoretically. As a result, it is shown that the performance of the unit is almost the same for the finned tubes with the same surface area even if the fin configuration is quite different. Influence of Fin Parameters on Melting and Solidification Jun 08, 2021 · Augmenting meting and solidification rates of latent heat storage unit (LHSU) is very much essential for its efficient operation. By the effective utilization of natural convection, rate of heat transfer can be enhanced and the conical shell is beneficent in this regard. Using fins further improves the charging and discharging rates.

Study on performance of a packed bed latent heat thermal Aug 01, 2006 · In thermal systems such as solar thermal and waste heat recovery systems, the available energy supply does not usually coincide in time with the process demand. Hence some form of thermal energy storage (TES) is necessary for the most effective utilization of the energy source. This study deals with the experimental evaluation of thermal performance of a packed bed latent heat TES unit Thermal Energy Storage by Using Latent Heat Storage 2.3.2 Latent Heat Storage . Latent heat is the heat released or absorbed by a body during a change of state without change of temperature, say from liq-uid to solid (as ice freezes) or from a liquid to a gas (as water boils) [2]. The storage capacity of the LHS system with a PCM medium is given by
