摘要：

The current research purpose is to study the solar air heater using aluminium cans with aluminium scraps and pebble stones as sensible heat storage material (SHM). The solar intensity, temperature difference of air inlet and outlet, heat transfer coefficient between aluminium can and flowing air and instantaneous thermal efficiency were studied for the mass flow rates of 0.025 kg/s and 0.0916 kg/s. Results reveals that the outlet temperature is 1.5 degrees C higher than the ambient after the sunset when SHM was used. The instantaneous efficiency and heat transfer coefficient were found to be better for 0.025 kg/s with aluminium scraps than the other cases. (C) 2019 Elsevier Ltd. All rights reserved.
