...Utkarsh Srivastava; Rashmi Rekha Sahoo This research explores the numerical investigation of melting processes in duplex and triplex tube latent heat thermal energy storage (LHTES) systems utilizing phase change material (PCM) enhanced with nickel foam and MXene nanoparticles. By incorporating...

... melting temperature. The thermal efficiency of LTESS is usually limited by poor heat conduction in PCM but enhanced by the natural convection of molten PCM. The natural convection increases the uniformity of temperature by mixing in a PCM enclosure and therefore increases the heat transfer rates...

... during the melting (charging) process. Inadequate melting in these systems reduces the thermal performance of LHTES systems. To facilitate and accelerate the melting process, the innovative design of such systems is a key. The present study proposes novel designs of toroidal tubes embedded in the LHTES...

... parameters viz., fin number, fin thickness, orientation and base thickness on melt fraction and operational time have been analyzed. The critical temperature considered for the study is 54.8 °C. The melting behavior of the PCM is simulated by using the volume of fluid (VOF) method. The design...

Liquid fraction distribution and melting front evolution for δ = 0.25, δ = 0.5, δ = 0.75 in a rectangular (top) and square (bottom) enclosure with Ω = 45 deg at t = 3600 s Liquid fraction distribution and melting front evolution for δ = 0.25, δ = 0.5, δ = 0.75 in a rectangular (top) and square...

..., whereas the melting time is reduced as the wall temperature increases. The Nusselt number increases sharply at the initial period of the fusion process, followed by a decaying trend with time until it stabilizes when the charging process is terminated. Increasing the cell diameter from 20 to 40 cm...

...Hamza Faraji; Mustapha Faraji; Mustapha El Alami The present paper reports numerical results of the melting driven natural convection in an inclined rectangular enclosure filled with nano-enhanced phase change material (NePCM). The enclosure is heated from the bottom side by a flush-mounted heat...
