Experimental and Numerical Investigation of the Influence of the Flow Rate on Heat Transfer Characteristic on the Plate Heat Exchanger

The paper proposes an experimental and numerical approach of analyzing on the influence of working fluid and mass flow rate on the heat transfer characteristic in plate heat exchanger by performing the experiment on an industrial counter flow plate heat exchanger with 59° chevron angle. In this study, numerical results obtained from Aspen HYSYS V10 Exchanger Design and Rating EDR were compared with experimental data and showed good arrangement. The effective heat transfer area is 4.2 m2. Water is used as cold fluid and oil is used as hot fluid with the counter flow arrangement. Cold water flow rate is controlled at different flow rate of 2 m3 hr, 4 m3 hr and 6 m3 hr. Hot oil flow rate is varied from 3.6 m3 hr to 5.2 m3 hr. The inlet temperature of cold water and hot oil to heat exchanger were kept constant at 50°C and 32°C respectively. The experimental and numerical results show significant effect of flow rate on heat transfer rate, overall heat transfer coefficient, and effectiveness. It is shown that the Aspen HYSYS V10 EDR is a reliable tool for investigation of heat transfer characteristic in the plate heat exchangers at various flow rate.
