Abstract:

Heat exchangers being one of the most important heat & mass transfer apparatus in industries like oil refining, power plants, chemical engineering etc. are designed with preciseness of optimum performance and long service life. The Project deals with the design and analysis of the Shell and tube heat exchanger in which we derive the optimistic and reliable conditions for a heat exchanger. We know that segmental baffle is well known to many people and engineers. By replacing the segmental baffle we are introducing helical baffle to improve the heat transfer rate and flow rate inside the shell and tube heat exchanger. Here we are considering the helix angles of 30o and 45o . The shell side zig-zag flow induced by the segmental baffle arrangement is completely eliminated in a helical heat exchanger. The flow pattern in the shell side of the continuous helical baffle heat

Keywords: The shell side zig-zag flow induced by the segmental baffle arrangement
