Extended surfaces, also known as fins are used commonly for heat transfer enhancement in energy storage and thermal management problems. A fin may improve the rate of by offering greater surface area. While performance a single-phase ambient such air is well-understood, relatively lesser work available on performance, including parameters effectiveness efficiency, when embedded phase change mat...

Abstract—The objective of this work was to develop a theoretical model to study the dynamic thermal behavior of a flat plate solar collector integrated with a phase change material (PCM). The PCM acted as a heat source for the solar system during low intensity solar radiation and night. The energy balance equations for the various components of the collector as well as for the PCM were formulat...

In this experiment effect of two full and half width sinusoidal inner tubes in triplex-tube heat exchanger with phase change material (PCM) was investigated. Length and diameter of the tubes have been chosen such that the area of each tube to be the same. Charging and discharging processes were carried out by inner tube, outer tube and both. Results indicated, PCM melting and solidification tim...

The enhancement of operating life cycle of electronic devices necessitates the development of efficient cooling techniques. Therefore, in the present work the effects of employment of Phase Change Material, in the adiabatic section of heat pipe for electronic cooling applications were experimentally and numerically investigated. Tricosane (100 ml) is chosen as PCM in this study, where Al2O3 nan...

The significance of latent heat thermal energy storage is more substantial when compared to sensible due its higher capability. In this paper, transfer enhancement techniques for melting (charging) and solidification (discharging) by using external fins internal–external a phase change material (PCM) in duplex triplex tube exchangers (DTHX TTHX) are investigated numerically. A two-dimensional a...
