The research that led to the creation of Ice Dragon Cooling began in the early part of 2007.  Dale McCants was pursuing his PhD in Mechanical Engineering at the University of South Carolina, and Andrew Hayes had left the Air Force Research Lab to do post-doc work on the project. The project began with the creation of the flow loop. This was built entirely from scratch. It could flow water/nanofluid at a flow rate of almost 50gpm through a 2in x 2in square channel. Inside the square channel was a heated flat plate that had thermocouples equally spaced down the center line in the direction of flow.  The loop also had a liquid-to-liquid heat exchanger that controlled the fluid temperature inside the loop. Data was collected at various flow rates. We also compared various kinds of nanofluids made up of different amounts of different nanoparticles to that of water. By knowing the fluid properties, flow rate, heat input, temperatures of the fluid and the plate we were able calculate the convective coefficient for the particular fluid. This let us compare the different fluids and determine which one was the best performing fluid.  We also had a LaVision laser system to investigate the flow field.

Test Loop

After performing tests on all the different types of nanofluids and water, we had to crunch a tremendous amount of data.
