Description
Summary:A centrifugal spray generator of singlet oxygen, O 2 ( 1 Δ g ), for driving a chemical oxygen-iodine laser was developed and its operation was experimentally studied. Modeling of the liquid separation from the gas flow showed that the separator designed could remove droplets larger than 0.5 μm from gas, which is very important for the laser operation. This result was confirmed by experiments. Experimental studies proved that O 2 ( 1 Δ g ) could be produced with a high efficiency (chlorine utilization 0.68–0.87 and O 2 ( 1 Δ g ) yield 0.35–0.7) even at very high generator pressures (25–70 kPa), which cannot be attained by other O 2 ( 1 Δ g ) generators.
