Computer Aided Nucleation Nozzle Design.

Abstract

As an aid to designing nozzles for use in the homogeneous seeding of clouds, the one-dimensional equations of motion for a compressible, inviscid flow of air and water vapor are solved together with the classical nucleation rate equations for any arbitrary nozzle profile. The occurrence of shockwaves at high initial humidities is sensed and transition calculated by the Rankin-Hugoniot shock relations. Onset of condensation in the nozzle is observable by plots of condensate versus distance; other thermodynamic parameters are also obtained. Results are compared with previous experimental findings and limitations of the design procedure are discussed. (Author)
