THEORY 



The Douglas C-S method solves the standard incompressible, steady 

 continuity and momentum equations for thin axisymmetric boundary layers. 

 This set of partial differential equations, with the addition of the 

 transverse curvature effects, is

where u = mean velocity component in the s direction (parallel 

 ^ to the body meridian) 



v = mean velocity component in the n direction (normal to 

 the body meridian) 



p = pressure on the body 



r = r_(s,n) + n cos a 



r = body radius 



X = axial distance measured from the nose 



V = kinematic viscosity of the fluid

u' = velocity fluctuation in the s direction
