The present paper describes the experimental results far aerosol-jet singlet oxygen generator with a twisted flux to separate the aerosol effectively. It was demonstrated that at 50 Torr pressure and 30 m/s velocity, there does not exist the aerosole in the flux at the reactor output, and singlet oxygen contribution constitutes 70%, not less. The numerical simulations results are given for supersonic COIL up to 50 Torr pressure in the nozzle input with and without inertia diluent in the main flux.
