Thermal storage unit with NEPCM involving numerical unsteady simulation
Case Studies in Thermal Engineering, 2022 In current study, the channel for purpose of air ventilating has been suggested with considering containers of paraffin. To attain faster process, nanoparticles (TiO2) were mixed with RT25 and single phase formulations were utilized which means that uniform concentration of NEPCM exist in all over the zones of paraffin.

Modeling for converting liquid NEPCM to solid phase with involving nano-powders
Case Studies in Thermal Engineering, 2022 The new code has been developed for simulating the freezing of nanomaterial with water base PCM. This code was based on Galerkin approach and style of grid depends on position of solid first layer. The two surfaces have been maintained at cold temperature and fins have been mounted to increase the space of cold area.
