Investigation of the Singlet Oxygen Generator with the Twisted Flow

Abstract

The results of the Singlet Oxygen Generator with Twisted Aerosol flow (TA-SOG) investigations are presented. The experimental results demonstrate TA-SOG output values exceed those of other types SOGs known from publications. TA-SOG outflow is aerosol-free all over the broadly ranged parameters even at a gas pressure over 100 Torr and velocity 100 m/sec. The maximal chemical efficiency was obtained as 70 percent. The reactor cross-sectional electronic energy flux exceeds 1.5 kW/cm2. Measured Singlet Oxygen (SO) yield was approximately 60 percent at the pressure 12- Torr at the measurement point distant by more than 10 cm of reactor outlet. Chlorine utilization exceeds 90 percent. All the listed parameters were obtained without any buffer at its outlet. It is directly connected to COIL supersonic nozzle not fearing BHP carryover. So, TA-SOG output and nozzle input pressures are almost equal without additional ejectors. TA-SOG model created provides atmospheric pressure of the spent solution at SOG outlet, which simplifies sufficiently the re-circulation system design.
