Comparison of Effectiveness of Two Different Setups of Double Pipe Heat Exchangers
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 9
Abstract
At present cost and performance are the two major factors which plays a vital role in the selection of any augmentation method of heat transfer. Cutting of triangular shaped fins is also very difficult to insert inside smaller annular pipes compared to that of the rectangular shaped fins. Cost spending for all other shaped fins except for rectangular shaped fins are more for cutting and welding purpose with respects their effectiveness. For given dimensions of the double pipe heat exchanger with selected rectangular fins, copper twisted tape is inserted into the inner pipe of the double pipe heat exchanger as first setup of heat exchanger. But second setup of heat exchanger is fabricated with copper twisted tape only without fins at the outside of the inner copper pipe in second heat exchanger. Comparing these two heat exchangers, effectiveness is more for first heat exchanger ie., it can carry out more heat from inner hot fluid to outer cold fluid than that of second heat exchanger which consists only twisted tape without fins. So by using fins in addition to twisted tape effectiveness can be enhanced.
