摘要：

To evaluate the performance of arcjet-type arc-heater as an atomic oxygen generator developed at the University of Tokyo, the number density of atomic oxygen was measured by laser absorption spectroscopy and by CFD analysis. As a result, oxygen was found localized off axis near the nozzle exit and gradually mixed with argon gas in the downstream region while being dissociated. Owing this slow mixing process, the maximum degree of dissociation of oxygen in the plume was estimated at unexpectedly small level of 0.01%. (C) 2004 Elsevier Ltd. All rights reserved.
