In this work, the melting process of compounds containing nanoparticles of NePCM in a square hole with different angles affected by two pairs of well-spring heat source on horizontal walls was numerically investigated. Four different configurations of elements were employed to investigate the effect of changes in the position of elements on the horizontal walls of the well-spring landscape on t...

A conical shell-tube design with non-uniform fins was addressed for phase change latent heat thermal energy storage (LHTES). The shell filled nano-enhanced material (NePCM). cone aspect ratio of the and were adopted as geometrical parameters. type volume fraction nanoparticles other investigated alumina, graphite oxide, silver, copper. finite element method employed to solve natural convection ...

In this modeling investigation, freezing of NEPCM inside a chamber with triangular cold cylinder has been scrutinized. With mixing copper oxide nano-powders and H2O, new material generated. To include the impact nano-powder shape, empirical correlations were utilized. For simulation such transient conduction mechanism, finite element approach was applied considering grid adaption. Amplitude top...

In the present modern world, use of electronic devices is extensively increasing for different applications, where thermal management these still a critical challenge due to rapid miniaturization, high heat flux and constantly rising temperature. Phase change materials (PCMs) based adopted, but low conductivity limits their in temperature-controlled devices. Nano-enhanced phase (NePCMs) can imp...

Nanoencapsulated phase-change materials (nePCMs) are investigated for enhancing thermal energy storage. However, the shell of these nanocapsules may fail due to stress developed during processes, leading melting enthalpy loss. To overcome this problem, SiO2 and Al2O3 coatings on Sn nanoparticles synthesized by atomic layer deposition (ALD). study influence thickness composition probability fail...
