Abstract
The preliminary visualization technique for a low density gas flow is discussed. The optical absorption phenomena of ultraviolet ray by ozone are applied. Ozone has a region of continuous absorption between 2000A and 3000A of an ultraviolet light wave length, with a noximium at 2537A. Therefore, the parallel ultraviolet light from a low pressure mercury lamp is injected from one side wall of a test section. In the reduced pressure test section, oxygen-ozone mixture jets are forced into from a nozzle. The ultraviolet light passing through the jets are absorpted. The radiation emerging, after absorption in the jets is transformed into visible light by fluorescent screen.
