Investigation of Hydraulic Behavior of PFHE Used for Cooling Application

Hydraulic behavior of plate fin heat exchanger with offset strip fin is investigated in this work. A lab scale set up of plate fin heat exchanger with offset strip fins is developed for the investigation. Hydraulic behavior of the considered heat exchanger is determined by conducting series of experiments. Mass flow rates of both the fluid, cold fluid inlet pressure and hot fluid inlet pressure are considered as input parameters. For different value of input parameter, value of friction factor and pressure drops are obtained. The correlations proposed by Maiti and Sarangi, Manglik and Bergles and Joshi and Webb are chosen as based correlations and values of pressure drop and friction factor obtained experimentally are compared. Finally, correlation for friction factor (f) is proposed to predict the pressure drop and friction factor.
