Determination of hydrodynamic parameters for some widely used mesh screen structures for the range of flow rates, using experimentally obtained correlation for pressure drop and to investigate the effect of charge pressure on these hydrodynamic parameters. Performance effect of different regenerator on a pulse tube refrigerator system was studied using the parameters derived for four mesh screens.
