Abstract
An experimental set up has been designed and built to investigate the alternating flow characteristics of a metallic regenerator with straight channels under isothermal conditions. The operational frequency of the system was run between (0.71-4.25 Hz). Detailed experimental data were obtained for the pressure drop. It is found that the pressure drop of alternating flow in regenerator is different than that of steady state unidirectional flow. The effect of frequency and size of the regenerator on the pressure drop is presented and discussed. The current results of the friction factor were compared to other studies from the literature employing alternating air flow in similar metallic materials.
