flow past sphere: surface pressure distribution
 
hallo, can anyone refer me to computed (or measured) pressure distributions at higher Reynolds numbers, say Re > 500. background: i need the time averaged pressure as a boundary condition for a linearized droplet deformation model. thanks a lot - roland

Have you looked in Hermann Schlichting's book "Boundary Layer Theory" yet? You ought to be able to find something there that suits you. Tons of stuff on spheres, plus many references.

axel, thanks for the hint. i checked the 7th edition (1979) where the only thing i could find was an experimental pressure distribution from o. flachsbart (1932) at high subcritical Re. so, i guess you are refering to a newer edition of this book? anyway, i will definitely try that. roland

Roland:

Yes, I also have the 1979 seventh (English) edition, republished by McGraw-Hill in 1987. The references of Chapter 1 (p.23 in my book) include several papers on spheres. My personal favorite is {1] Achenbach.

You can adjust the Cp of any subsonic compressible result via the Prandtl-Glauert Rule to get incompressible Cp.

If you speak German (your name sounds like it) you can even read the German originals. There are quite a few!
