Abstract

A centrifugal bubbling SOG generated gas flow with partial oxygen pressure up to 40 torr at singlet oxygen yield about 60% and residual chlorine less than 10%. At initial BHP temperature 260K and ratio of chlorine molar flow rate to BHP volumetric rate of 1mole/litre the output BHP temperature was 290K and water vapor fraction relative to the oxygen was 15%. An oxygen flux up to 6 mmole/s per 1 cm² of the bubbler surface has been attained. An ejector nozzle bank generates gain medium flow at Mach number ~2 and temperature lower 200K with small signal gain higher 1%/cm. Ejector COIL powered by centrifugal bubbling SOG demonstrated ~25% of chemical efficiency with specific power 6 kW per 1 litre/s of BHP volumetric rate.
