Article
Full-text available
Thermal analysis for the charging/discharging process of PCMs in different encapsulation geometries for free heating applications is performed. PCMs; sp07 and sp11 for cold climate conditions are simulated with Al2O3 and CuO nanoparticles (NPs) in circular, elliptical, rectangular, and square physical models. Complete mathematical equations of the...

Herein, free cooling an application of thermal energy storage is investigated through theoretical observations of air being cooled after passing over encapsulated phase change material (PCM). The impact of encapsulation geometry changes from circular to; rectangular, square, and elliptical shapes is studied for the PCM solidification and melting cy...
Article
An experimental investigation is presented on the preparation, and characterization of nanocomposites of the phase change materials (PCM) sp24, sp26 and sp29 with Al2O3 and CuO nanoparticles (NPs). The product samples are characterized and evaluated during melting and solidification cycles. The effects of the nanoparticles in the PCMs are observed...

The heat transfer is studied during the melting and solidification of sp11 and sp24 phase change materials in different container shapes. The materials are further mixed with nano-alumina and nano CuO enhancements. We aim to identify the most favorable phase change material for free-cooling in summer and free-heating in winter. Ansys Fluent 20.2 is...
Article
World over, research inventions have spiraled around sustainable energy solutions including the advent of phase change material based thermal energy storage systems. The application of these systems in thermo-regulating systems such as refrigeration, air conditioning, personal thermal comfort, building and construction, has been widely accepted. Mo...
Article
Phase change material thermal energy storage is a potent solution for energy savings in air conditioning applications. Wherefore thermal comfort is an essential aspect of the human life, air conditioning energy usages have soared significantly due to extreme climates, population growth and rising of living standards. Resultantly research efforts ha...
