Abstract
The heat exchanger is the most common equipment in the industry. Nowadays, CFD simulation has been used widely to predict the performance of heat transfer. The accuracy of the CFD depends on several factors such as simulation parameters, models, and quality of the grid. The heat exchanger in industrial application has big heat transfer capacity, since it consists lot of tube and big shell size. In this study, the fluid heat transfer on the tube is represented by uniform wall tube temperature. The objective of this works is to evaluate the performance of the SST kco turbulent and by applying heat transfer simulation of fluid on the tube side represented by uniform wall tube temperature. This present work compared CFD simulation and Experimental study. While the working fluids which are used in the experimental study are cooking oil in the shell and exhaust gas in the tubes. The constant of SST kw turbulent are cmu: 0.09, c1: 1.44, c2: 1.92, and sigma epsilon 1.3. The CFD simulation result shows in 50 s simulation that the temperature of cooking oil is from 48 °C to 54 °C. This tendency has good agreement with the experimental study.
