Abstract

MELTING of Cyclohexane-Cu nano-material in a porous square cavity is studied numerically in this paper.The initial temperature of the cavity is Ti that is equal to MELTING temperature of NANO-PCM (phase change material), Tm, The horizontal walls are adiabatic. Suddenly the left wall's temperature changes to Th>Tm. The effective parameters in this case are Ra, j and ε which appear in the nondimensionalized equations. Nondimensionalized governing equations are obtained based on the Darcy model; a control volume approach is used for solving these equations. The effect of the variation of mentioned parameters (50 ≤ Ra ≤ 500, 0 ≤ j ≤ 0.05 and 0.1 ≤ e ≤ 0.6) is investigated on the heat transfer rate, fluid flow, isotherms and MELTING time of NANO-PCM. The results show that changing any of the parameters will affect the increase or decrease of heat transfer rate and MELTING process time.For example variation of e has considerable effect on melt fraction in cavity with time. The results show that MELTING of PCM is prolonged when nano-particles are added. The results show that, increasing the Ra number, enhanced the power of natural convection heat transfer and the rate of NANO-PCM MELTING in the cavity and therefor deforms the MELTING line.
