Abstract
CFX simulation is a powerful tool for the thermal hydraulic design and analysis of heat exchangers. The shell and tube heat exchanger is the most common type of heat exchanger, and is widely used in high pressure applications. However, the computation load is usually too heavy to simulate a whole shell & tube heat exchanger for the conventional modelling method.
Authors employed single tube geometry for analysis. The processes in solving the simulation consisted of modelling and meshing the basic geometry of single tube heat exchanger using the ANSYS 14.0 package CFX. Then, the boundary condition were set before simulation based on the experimental parameters. They used the same parameter of experimental at constant material of hot fluid (Servo Prime Oil), and varied with cold fluid volume fraction (Water). Accordingly, this paper presents the simulation of heat transfer in shell and tube heat exchanger model and validation to heat transfer in shell and tube heat exchanger studies unit no. 5 of thermal power station Ukai (TPSU) for the analysis.
