판형열교환기의 열전달특성 및 압력강하에 관한 연구

초록

This study aims at analyzing numerically on heat transfer characteristics and pressure drop of plate heat exchanger(PHE) using the Phoenics 3.1 VR Editor for the standard model. Computations have been carried out for a range of chevron angle from 30° to 60°, inlet velocity from 0.03m/s to 0.63m/s and the height of corrugation from 0.0045m to 0.0060m. The results show that both of heat transfer performance and pressure drop increase as chevron angle increases. The reason is that higher troughs produce higher turbulence and a higher heat transfer coefficient in the liquids flowing between the plates. As inlet velocity from 0.03m/s to 0.63m/s increases, heat transfer performance and pressure drop increase parabolically. Thirdly, as the height of corrugation increases, both of heat transfer performance and pressure drop decrease for the decrease of velocity.
