기구적 설계변수에 따른 판형열교환기의 성능특성에 관한 해석적 연구

Plate heat exchangers have been widely adopted in many industrial applications due to their compactness and high efficiency. Even though the studies on the plate heat exchangers have been performed by many researchers, the studies on the geometric parameters except chevron angle are very limited in open literature. In this study, a simulation algorithm was developed using empirical correlations, and the predicted data were compared with the measured data to validate the model. The effects of the geometric parameters on the heat transfer and pressure drop characteristics of plate heat exchangers were investigated analytically by varying the design parameters such as the chevron angle, plate pitch and aspect ratio at the constant process conditions. In addition, the optimum design methods for the plate heat exchanger were discussed.
