Experimental Analysis of Heat Transfer Characteristics and Pressure Drop through Screen Regenerative Heat Exchangers

This study investigated the effect of reducing screen thickness by rolling. The experiments were performed on 250 and 325 mesh screen using helium gas. Reynolds numbers, based on hydraulic radius, Re, were between 10 and 100. Both the Colburn factor, StPr2/3, and friction factor, f, decreased as the screen thickness was reduced. A correlation for predicting f was developed. The coefficient of drag per screen, C D , remained nearly unchanged for thicknesses reduced not more than 30 percent. The decrease in Colburn factor was significant for Re less than 40. For 40 < Re < 100 the decrease in Colburn factor was less than the bounds of experimental uncertainty.
