Enhancement in Heat Transfer Rate in a Pipe in Pipe Heat Exchanger Using Helical InsertBy Manish Lal, Pranit Braganza, Aishwarya Singar, P.B. Lanjewar
Abstract: AbstractHeat transfer enhancement techniques are frequently used in heat exchanger system in order to increase the rate of heat transfer and improve the thermal performance of the system. This paper contains experimental study on enhancement in heat transfer rate using helical insert. The inner tube used was of copper with inner and outer diameter of 11.8 mm and 12.7 mm, respectively, and outer tube was galvanized iron, which was insulated …
