H-Disk Aluminum Prototype Heat Transfer Test Summary
The aluminum H-disk was instrumented with heaters (156 ohm on average) and 100 ohm platinum RTD's. Each heater supplies the heat of a double sided H-wedge. Since the flow splits into two flow directions at the inlet fitting, only half of the cooling channel is fully instrumented with RTD's. The other path has a single RTD to check for flow balancing. These items were installed after Greg Derylo petformed the first pressure drop tests. At the time of the test, the desired adhesive for gluing the two halves of the channel together was not available. Therefore, 5-minute epoxy was used on the inner and outer diameters of the halves. Tape was used to set the gap between the two halves. This form of attachment does not make a strong bond between the two halves so the differential pressure between the inside and the outside of the channel was limited to a couple of psi. Therefore, the tests were not conducted in a vacuum.
