The Interphase Transport Phenomena Laboratory (ITP), directed by Dr. Frederick R. Best, has more than 6,000 KC-135 0-g parabolas of experience in testing fluid systems under weightless conditions. The ITP laboratory has extensive experience in the construction and testing of microgravity fluids experiments including numerous KC-135 and more recently C-9B projects for the Air Force Phillips Laboratory, NASA Johnson Space Center, Foster-Miller Inc., Creare, Boeing, and the NASA Center for Space Power have all been successfully completed. The ITP was a partner in a shuttle fluids experiment, which successfully flew in November-December 1997. Other projects include "Two Phase Separator Testing in Support of a Zero Gravity Waste Water Processing System Shuttle Flight Experiment," and "Low Gravity Phase Separator Development in Support of ISS Propulsion Module Propellant Transfer." One of our close partners, The Center for Space Power develops power and thermal management technologies by forming working teams of university, industry, and NASA personnel. The Center is presently working on various projects including zero gravity two-phase flow systems. The ITP has a number of research projects dealing with zero gravity two-phase flow that include flow regime investigations, manifold stability and phase separation. The lab makes use of extensive zero gravity flight-tested instrumentation to carry out research projects. Dr. Best's area of research includes thermal management of spacecraft. Johnson Space Center (JSC) identified a fixed container, passive vortex phase separator system developed by Dr. Best at Texas A&M as being applicable to their proposed Immobilized Microbe Microgravity Water Processing System (IMMWPS). IMMWPS is in the process of being manifested on STS. Other shuttle projects completed by the CSP team include flying a loop heat pipe on STS-87.
