摘要

Abstract

An analytical model for convective and radiate heat transfer between the hot gas and the ejector structure was established. The variation of wall temperature and heat flow of the cylindri- cal and secondary-throat ejectors in the case of different cooling water flow is analyzed. The range of mass flow rate of the cooling water needed for heat protection of the ejector was determined on the basis of detailed heat transfer analysis. The computational results show that the simulation results are consistent with the experimental measurements obtained in the vacuum cabin.
