Nuclei in the Exhaust of a Jet Engine
Surveys were made of condensation nuclei, freezing nuclei, and water vapor concentrations in the exhaust wake of an F80 jet aircraft. Condensation nuclei concentrations were found to be maximum in a region of 50 to 75 ft aft of the tailpipe, with secondary maxima appearing at approximately 150 ft. No freezing nuclei were found, although observations indicated the possibility that they were present but inhibited by exhaust constituents.
