Abstract- Heat transfer enhancement of dimple, corrugated and plain tube is done in this study. Here, voltage is varying from 60-100 v. There is wide increase in heat transfer from corrugated tube after 80 Volts. Hence, we have high heat transfer in the corrugated tube at higher voltages. Also, I use dimple tube in this study and I try to find out the heat transfer coefficient of dimple tube and corrugated tube and plane tube. I use natural convection set up for this study and I find out Corrugated tube shows good results as compared to other tubes.
