An Analysis of Transonic Viscous Inviscid Interactions on Axisymmetric Bodies with Solid Stings or Real Plumes

A numerical and theoretical investigation Of pressure 
distribution predictions over arbi trary bodies of revolu tion in 
transonic flow has been carried out. Special features of the 
study include a comprehensive survey of previous and contemporary 
efforts in this direction and a detailed description Of 
combined viscous/ inviscid digital computer program which was 
developed to iterate between the inviscid transonic and the 
viscous portions of the analysis . For attached boundary layers 
the calculation procedure has been fully automated for both 
subcritical and supercritical cases, and predicted pressure 
distributions agree well with data . The entrainment effect of a 
real plume was modeled using the mixing theory first developed 
by Chapman and Korst. This method shows promise when its 
results are compared with data, but further work must be done 
to more correctly model the turbulent mixing of the two jets .

The work reported herein was conducted by the

Systems Command (AF'SC) , under Program

The author would like to thank all of the people 
who, at some or another, gave him assistance during his 
work toward the completion of this dissertation. Space allows 
mention of only a handful, unfortunately. In particular, 
sincere gratitude is extended to my advisor, Dr. Jain—Ming 
Wu, who has always provided me with solid technical advice 
and continual encouragement . Two of my co—workers. Dr. David 
L. Whitfield and Mr. Robert C. Bauer of the Propulsion Wind 
Tunnel Facility, ARC), Inc., are especially to be thanked for 
their aid, particularly during the past two years. Formula— 
tion of the Combined program would have been impossible with— 
out the aid Of Mr. Karl Kneile, and the same may be said about 
the plume Entrainment program and Mr. John Fox's efforts
