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.
