Design and CFD analysis of Shell and Tube Heat Exchanger Using Plain tube and Corrugated tube

Mechanical Engineering

Shell and tube heat exchangers are used for convective heat transfer between two fluids, where one fluid flows through the tubes and other flows in the shell. This paper mainly focuses on improving the heat transfer capability in a shell and tube heat exchanger by varying tubes geometry using ANSYS Fluent. Study carried out the thermal design on the heat exchanger working in the company. Corrugated tube were employed instead of plain tube through a shell and tube heat exchanger. Corrugated tubes were investigated for heat transfer coefficient is studied for a shell and tube heat exchanger made of corrugated tube by using software and convective Heat transfer coefficient (HTC) of plain tube is compared with corrugated tube. Maximum convective HTC was observed for heat exchanger. This paper mainly focuses on improving the heat transfer capability in a shell and tube heat exchanger by varying tubes geometry. Study carried out on the design of the heat exchanger and by increasing overall HTC to prove more heat transfer is possible.
