Performance Analysis of Helical Coil Heat Exchanger Using Numerical Technique
Keywords:
Helical Coil, Temperature Drop, Heat Transfer Rate, Nusselt Number, Coil DiameterAbstract
Helical coil heat exchangers are widely used in applications requiring large heat transfer area per unit volume. In present work, CFD simulation of helical coiled heat exchanger has been done. The diameter coil of heat exchanger has been varied along with mass flow rate. Water at 332 K has been considered at inlet. Parameters such as temperature drop, heat transfer rate, heat transfer coefficient and Nusselt number have been found out and compared for the geometric variations and variation in mass flow rate. It has been found out that temperature drop decreases for decrease in diameter of coil and also for increase in mass flow rate whereas heat transfer rate increases with increase in coil diameter and mass flow rate.
