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 30° and 45°.
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 exchanger is rotational and helical due to the geometry of continuous helical baffles.
In this project we design the 3d model of the shell and tube heat exchanger by solid works and analyze using ANSYS by using computational facilities.
The results obtained in this project shows us that the desired properties from a heat exchanger i.e., high heat transfer coefficient and low pressure drop are more effectively obtained in a helix heat exchanger
