Non-Equilibrium Flow Experiments in the USC Iodine Flow.

Abstract

The study of nonequilibrium flow phenomena using a hypersonic flow of iodine vapor was originated under an AFOSR URI grant. At the end of that grant the major components of a large iodine vapor tunnel were available and assembled. There were insufficient funds to provide a satisfactory iodine resistant coating for the interior of the tunnel. Several inexpensive coatings were investigated but were not satisfactory. The decision was made at that time to validate the cryogenic pumping performance of the iodine hypersonic tunnel by using CO . In parallel a search was initiated for the approximately twenty-five thousand dollars in equipment money required to coat the interior of the tunnel to permit operation with iodine. The report of the work appears here. The pumping performance of the facility is very satisfactory and exceeds the design requirements. As it turns out the University of Southern California, based on the promising pumping results, has now been able to provide sufficient funds to complete the tunnel coating so that by early 1997 the facility will be able to operate on iodine. The University is also at present supporting the work of a student to complete the facility.
