The characteristics of heat transfer and pressure drop of plate heat exchanger according to the channel space

Abstract

The study aims to interpret the thermal and pressure drop characteristics of plate heat exchangers to determine the geometric design parameters such as the channel space. In this study, heat transfer performance was numerically studied with respect to the flow pattern and channel space. The results from numerical analysis indicated that the j factor was linearly decreased with flow rate over every cases. As the flow increased within channel spaces, the j factor was found to be decreased linearly. And the f factor is linearly decreasing with the increase of mass flow rate. The f factor was constant with flow rate over every cases. As the flow increased within channel spaces, the f factor was found to be constant.with respect to the flow pattern and channel space.
