Discharging process within a renewable energy storage system via numerical simulation in existence of water based nanomaterial

To develop the sinusoidal container, three rectangular fins were utilized in current work to boost the rate of freezing. The mixture of H2O and CuO nanomaterial were used as NEPCM. FEM modeling for various ranges of size and concentration of nanoparticles have been presented. Good agreement in validation test has been reported. The longest process belongs to the water case and it takes 303.76 s to complete the process. With change of dp from 30 nm to middle size, the required time drops about 19.95 %. Dispersing nano-powders with the best size and greatest concentration leads to lessening of needed time by about 41.21 %.
