Parametric Comparison of Heat Transfer in Helical and Straight Tube-In-Tube Heat Exchanger

Suraj R. Gurav

Abstract: Helical pipes can be used for heat transfer enhancement in heat exchangers. The purpose of this work is to compare tube-in-tube helically coiled heat exchanger with a straight tube heat exchanger. In current work the fluid to fluid heat exchange is taken into consideration. The actual experimentation is carried out on tube-in-tube helical coil heat exchanger and tube-in-tube straight heat exchanger by keeping mass flow rate constant for both the fluids. The results were plotted graphically for comparison of heat transfer in both heat exchangers.
