Heat Transfer and Pressure Drop Characteristics of Finned Tube Banks in Forced Convection (Comparison of Heat Transfer and Pressure Drop Characteristics of Serrated and Spiral Fins)
要約
In recent years, requirement for the reduction of energy consumption has been increasing to solve the problems of global warming and shortage of petroleum resources. In the power generation field, thermal power generation occupies 60% of the power generation demand, so the improvement of thermal efficiency is of considerable importance. In this article, the heat transfer and pressure drop characteristics of finned tube banks used for heat exchangers in thermal power generation plants were studied experimentally. Serrated finned tube banks for improvement of higher heat transfer and conventional spiral finned tube banks were tested under the same test conditions. Empirical equations to predict the heat transfer coefficient and the pressure drop were proposed.
