Heat Exchanger Behavior in Non Uniform Flow

Abstract

An experimental study of a fin-and-tube heat exchanger was performed. To this end a test rig was constructed to evaluate the heat transfer capacity on the air side and the water side of the exchanger. The test rig and the measurement technique were devised for non uniform inlet flow. The resulting data was used to study the impact of the non uniform flow on the heat exchanger performance. Different types of non uniform flow were studied over a range of Reynolds numbers. The fin type present in the heat exchanger used in this research is an adapted inclined louvered type.
