Influence of Branch Angle on the Phase Change Material Solidification Process in A Heat Exchanger with Branch-Shaped Fins

Abstract

Globally, there is a growing energy demand. It's a figurative way to measure a country's progress. Investigating alternative energy sources is crucial because fossil fuel supplies are finite. The storage of the energy produced by renewable energy sources is the primary issue. The advancement of energy storage technologies is crucial for both storing the energy that has been obtained and for maintaining the energy's flow. One of the most effective methods of storing thermal energy is through the use of phase-change materials in latent heat thermal energy storage systems. When these substances experience a phase shift, they store heat. The purpose of this work is to examine how the phase change materials in a double-pipe heat exchanger solidify about the branch angle of the fins. The results reveal that the branch-shaped fins with a branch angle of 9 degrees yield the best output for the rate of heat transfer during the solidification of phase change material. The results compare the rates of heat transmission during solidification for branch-shaped fins with various branch angles. Because of their capacity to store and release thermal energy during phase transitions, phase change materials, or PCMs, have attracted a lot of attention for use in heat exchangers. In this work, the effects of branch angle fluctuations on a PCM's solidification process inside a heat exchanger with branch-shaped fins are examined.
