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.
