Passive Heat Transfer Augmentation Methods in Circular Tube

[Puja B. Pise,R. S. Shelke] Volume 1: Issue 2, April 2014

Abstract:-
The present paper is a review of the passive heat transfer augmentation in circular tubes used in the recent past and these techniques will be useful to designers while implementing in heat exchangers. In passive techniques, where inserts are used in the flow passage to increase the heat transfer rate, are advantageous compared with active techniques, because the insert manufacturing process is simple and cheap and these techniques can be easily employed in an existing heat exchanger.
Index Terms:-
circular tube, inserts, Passive heat transfer.
