Abstract
The pattern of the flow of a gas that is injected into a gaseous stream is made visible by causing the flow of the injected gas to become luminous; and, therefore, to be visible, detectable, and recordable. This luminosity is accomplished by producing long-lifetime (metastable), excited-state species (atoms or molecules) of the main gas flow upstream of the injected gas.
