Abstract Two numerical models are accomplished to predict thermal effectiveness of a novel solar heater with and without paraffin-based on the latent heat storage. The conservation equations with enthalpy transforming method of phase change material (PCM) are analyzed using finite-volume with an explicit scheme. The influence of the main parameters is investigated such as; airflow rate ranging of ( 0.6 ≤ m ˙ a ≤ 1.8 ) kg/min, and heat flux ranging of (625 ≤ Is ≤ 825) W/m2. The results found that the air temperature rise is proportionate to the airflow rate inversely, during the charge/discharge processes. It was concluded that the useful power and the thermal performance are significantly depended upon the solar flux with airflow rate in both models. Moreover, the thermal effectiveness of the collector without and with paraffin was approximately (33.8 – 73.15)%, and (31.3 – 66.77)%, respectively, under the range of the studied parameters. It was noted that the decreased thermal efficiency is (5–7)% with PCM by absorbing the stored energy and releasing it to the system during sunset. To verify the accuracy of experimental and numerical results under the same operating conditions with a mean error of effectiveness with and without PCM was identified of ±6.4% and ± 8.6%, respectively, and the results were acceptable.

Abstract This paper aims to investigate and analyze the thermal performance of a double-pass solar air heater using multiple rectangular capsules filled with paraffin wax-based on a phase change material PCM. An indoor projector simulator was used to test a new system during the charge/discharge process. In order to verify the accuracy of these readings, a mathematical model based on finite-volume scheme SIMPLE algorithm was applied to solve the three-dimensional forced convection turbulent flow in the double-pass solar heater. The computational results were in reasonable agreement with the experimental readings. The investigations were carried out at various airflow speed of (0.6, 0.9, 1.2, 1.5, and 1.8) kg/min and three solar irradiance intensities of 625, 725, and 825 W/m2. The results showed that the increased airflow rate leads to delay in the melting period and decrease melting temperature of the paraffin during the melting period. Furthermore, it can be detected that the optimal discharging period and the air temperature rise of the heater were reached of: 3hr with (17.95–3) °C, 2 h with (14–3) °C, and 1.25 h with (11–2.5) °C, for various solar intensity of 825, 725, and 625 W/m2 at the same airflow speed of 0.6 kg/min, respectively.
