Investigation the Performance of Cross Flow Heat Exchanger

Dr. Sadiq Elias Abdullah

Abstract: In this study the performance of cross flow heat exchanger staggered tube bank arrengment are experimentally investigated. Four sets of tube bank consisting of 24 tubes, six rows each four tubes, are used for all experiments. Creating a number of (14, 29, 59) V-grove shape of one mm depth on outer surface of three sets while the fourth remain as it is smooth. Reynolds number based on maximum velocity in tube banks varied from (1380) to (51380) while heat flux supplied from ( 10) to ( 120) W/m2 by steps of 10s varied. The heat transfer results of a smooth tube bank tests matches with other researchers are in good agreement. Meanwhile, other sets shows that the heat transfer increase with increases of Reynolds number, while non dimensional pressure drop decrease with increases of Reynolds number. A new Nusselt number-Reynolds number correlation was found.
