Heat Transfer Enhancement In Pipe With Passive Enhancement Technique

  Srinivas Valmiki

Abstract— The heat exchangers are used to enhance heat transfer by providing high heat fluxes or heat transfer coefficient. One of the most important techniques used is passive heat transfer enhancement technique. These techniques when adopted in Heat exchanger proved that the overall thermal performance improved significantly .Helical wire coil insert in plain tube have been experimentally studied in order to improve the heat transfer and overall thermal performance of heat exchanger The present experimental work are carried out with copper and aluminum wire coil inserts by varying pitches of 1 cm, 2cm and 3 cm respectively. The work includes the determination of heat transfer coefficient for various wire coil inserts with varying pitches and different materials. A performance comparison between wire coils inserts and plain tube has shown that wire coil inserts perform better than plain tube to enhance the high heat transfer.

Keywords- Heat transfer enhancement, wire coil inserts, passive enhancement technique
