20. ABSTRACT (Continue 



ary and Identity by block i 



Static pressure distributions, mean velocity profiles, distributions 

 of turbulence intensities, and Reynolds stresses, spatial correlation co- 

 efficients, and the Taylor microscale of turbulence were measured across 

 the stern boundary layer of an axisymmetric body with an inflected stern. 

 A theoretical and numerical iteration scheme, which uses the boundary 

 layer and open wake displacement body, is found to model satisfactorily
