About Us:

Fluids Inc. International, comprised of four individuals in their senior design class at FAMU/FSU College of Engineering. The group; Dante' Fillyau, Jason Orrock, Kevin Williams, and Kareem Williams, was given this because it was known that these individuals could handle such a project.

The Project:

The project as it was known is to reengineer/ redesign the present oil cooler used on the QS15 Cummins Engine. List below are the problems that need to be faced throughout this year long project.

Objective:

Design a test bench

> Must emulate current engine conditions
> Purpose is to test various oil cooler designs

Redesign current oil cooler

> Increase effective heat transfer
> Reduce corrosion due to the coolant

Explanation of Objective:

After a plant visit to Cummins Engines Technical Center in Columbus, Indiana the scope of this project has been defined. It has been discovered that the problem lies within two specific areas: oil cooler corrosion and ineffective heat transfer.

The oil cooler corrosion issue is due to the variation in the worldwide use of coolants. Because of location, finances, and access to high quality coolants, the oil cooler is susceptible to a wide range of “low grade” coolants. Low grade insinuates that there are high levels of corrosives in the coolant, which eventually leads to a mechanical failure locally within the cooler itself. To date, the composition of the most corrosive coolants is: Columbus, IN tap water w/ 1.5% penticool3000, 1000 ppm chloride 500 ppm sulfates.

The second issue that is to be addressed is that of ineffective heat transfer. This is due to a combination of elements that include; flow rate, cooler type, effective surface area, and material selection and others. The overall scope of this part of the problem can be improved through the modification of these areas.
