CFD Simulation of Heat Transfer in (STHE) Shell and Tube Heat Exchanger

Computational Fluid Dynamic (CFD) is a useful tool in solving and analyzing problems which involve fluid flows, while shell and tube heat exchanger is the most common type of heat exchanger and widely used in oil refinery and Auto mobile industries and other large chemical processes because it suit for high pressure and temperature application. The processes in solving the simulation consist of modeling and meshing the basic geometry of shell and tube heat exchanger using the CFD package ANSYS 14.5 meshing. Then, the boundary condition will be set before been simulate in Fluent 14.5 based on the experimental parameters. Parameter that had been used were constant mass flow rate of cold water and varies with mass flow rate at 0.0177 kg/s, 0.0089kg/s of hot water. Thus, this research presents the simulation of heat transfer in (STHE) shell and tube heat exchanger model and validates the heat transfer in Shell and Tube Heat Exchanger using baffles or without baffles making the flow counter and parallel. The CFD model is validated by comparison to the experimental results within less error.
