Complex turbulent flow and heat transfer characteristics of tube with different types of internal longitudinal fins in EGR cooler

  Sourav Kumar,  Saurabh Kumar

EGR coolers are made up like the shell tube heat exchanger models with the hot exhaust gas being passed through the tubes and the coolant brought into and taken out of the shell chamber. For efficient cooling, several techniques are implemented. However, providing fins of different cross-section areas inside the tubes. In this paper, we will be studying the effects on the flow of the exhaust gas inside the tubes due to a single tube and also the heat transfer that takes place while it interacts with the coolant available in the shell chamber. The focus will be kept on understanding the flow patterns and the heat energy interactions between these fluids. The entire study will be carried on CFD and implemented by using ANSYS Fluent 14.5. The main motive of the study will be to utilize the turbulence generators, in our case fins, and to get a comparative study with and without them.
