Correlation for Pressure Drop Prediction of Flow Through Heat Exchanger Fins
Keywords:
Pressure drop, Heat exchanger fins, CorrelationAbstract
This research studies the pressure drop of the gear oil flows through the heat exchanger fins. The designed variables consist are pitch length, fin height, fin inclination angle, oil flow rate, and oil temperature. The study has been investigated based on computer software simulation. The results found that, the pressure drop increased as increasing of the oil flow rate and deceasing of the oil temperature. Consideration of the fin size effects, it is found that, the pressure decreased as the pitch length, fin height, and fin inclination angle are increased. By sorting of fin size effects that dominate on pressure drop in are oil flow rate, oil temperature, pitch length, fin height, and fin inclination angle, respectively. The simulation results have been taken to formulate the correlation for predicting the pressure drop. It is found that the developed correlation gives an average accuracy in calculating of 94% compare with experimental data.
