Numerical simulations using the computational fluid dynamics (CFD) software ANSYS Fluent were undertaken to characterize the airflow and temperature distribution in a natural convection thermal energy storage refrigerator. The model compared the household refrigerator temperature stability with...

The current numerical study is conducted to analyze melting in a rectangular closed enclosure by subjecting the bottom wavy surface to a uniform temperature. The cavity vertical walls and the top wall are insulated while the bottom wall is maintained at temperature TB = 38.3 °C. The...

Transient three-dimensional heat transfer numerical simulations were conducted to investigate a hybrid PCM (phase change materials) based multi-fin heat sink. Numerical computation was conducted with different amounts of fins (0 fin, 3 fins and 6 fins), various heating power level (2 W, 3 W...

PCMs (Phase change materials) are used to enhance the thermal storage capacity of building walls, decrease indoor air temperature fluctuations, and shift peak heat transfer rates to off-peak times. PCM location within building walls is recognized to be critical for the optimum performance of the...

Microencapsulated phase change material with a low supercooling degree is one of the increasing important researches as well as industrial application for thermal energy storage. This study develops a novel and low supercooling microencapsulated n-octadecane (MicroC18) with n-octadecyl...

A series of microencapsulated phase change materials (MicroPCMs) with n-octadecane as core were successfully fabricated by suspension-like polymerization. The influence of initiator type and polymerization temperature on MicroPCMs were investigated systemically. The morphology of these...

The possibility of using magnesium based eutectic metal alloys as phase change material (PCM) for thermal energy storage (TES) in concentrated solar power (CSP) applications is analysed. An extensive thermophysical characterization of the Mg–51%Zn eutectic metal alloy between room temperature...

In this study, a novel Li-ion battery pack design including hybrid active–passive thermal management system is presented. The battery pack is suitable for using in hybrid/electric vehicles. Active part of the hybrid thermal management system uses distributed thin ducts, air flow and natural...

Thermal energy storage composites were developed by incorporating granular phase change materials (PX25 from Rubitherm®) into cement paste. Without prevention, however, a significant amount of phase change material (paraffin) leaked from the PX25 during the fabrication process. To prevent...

An analytical solution of a latent heat storage unit (LHSU) consisting of a shell-and tube was obtained by using the Exponential Integral Function and the variables separation technique. The working fluid (water) circulating by forced convection inside the inner tube charges and discharges the...
