Virtual Heat Transfer Enhancement

> Through the research and calculations done by Fluids Inc., we have developed several different methods to enhance the heat transfer and reduce the corrosion of the Cummins QSX15 diesel engine oil cooler. When Fluids Inc. first received this project, we set out to determine the dominating element of this heat exchanger. In heat exchangers, there is a dominating element that has a significant effect on the heat transfer. This dominating element is the backbone of the heat transfer. To provide optimal heat transfer of a heat exchanger, the thermal resistance of the dominating element must be decreased. After this discovery, we focused on coming up with different scenarios that would decrease the thermal resistance. Increasing the effective area and/or convection coefficient of the oil side will decrease the thermal resistance of the oil. To decrease the thermal resistance of the oil side, we thought of several ways to modify the current oil cooler. We also utilized three different materials to combat the corrosion problem.

> All calculations and parameters for the different design configurations are based on one oil cooler. This site will allow you to investigate the design packages that Fluids Inc. has developed. See Material below.
