CFD Analysis of Conical Coil Tube Heat Exchanger with Varying Cone Angle
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
Now-a-days heat exchangers have become indispensable in various fields of engineering such as in air conditioning, power stations, chemical plants, automobiles, etc. It necessitates the compact size along with the high performance of the heat exchangers. This work aims to study on passive technique of heat transfer enhancement by some variation in geometry. In this work the heat transfer and pressure drop analysis has been done for conical coil with varying cone angle. The cone angles taken for the study are 0° i.e. simple helical coil, 30°, 60°, and 90°. The comparative study of these coils have been done under three different flow rates i.e. 60 lph, 130 lph, and 200 lph for the hot fluid inside the tube. The analysis is done by CFD simulation in ANSYS Fluent 14.5 considering a double pipe heat exchanger where cold fluid is flowing on the outer portion of heat exchanger with a flow rate of 200 lph in each case. It has been observed that heat transfer coefficient is maximum in case of simple helical coil while pressure drop is minimum in case of 30° conical coil.
