Abstract
The heat exchanger is an important device in almost all of the mechanical industries as in case of process industries it is key element. Thus from long time many researchers in this area are working to improve the performance of these heat exchangers in terms of heat transfer rate, keeping pressure drop in limit by using various techniques. This project work deals with of such techniques keeping focus on passive augmentation techniques used in heat exchangers. Here the wire coiled turbulator and pin wire coiled turbulator are used to enhance the heat transfer rate in the double pipe heat exchanger by changing the flow of a liquid. Tests to be conducted at various mass flow rates by controlling the flow control valve, for the following valve opens (25%, 50%, 75%, 100% valve open). Results may indicate that the heat transfer rate enhances inversely with the pitch of the wire coiled turbulator and directly proportional to the mass flow rate.
