Hi all, Does anyone know of any correlations to estimate the velocity in the narrow gap area of an eccentric annulus? I know the velocity is lower in this area and heard that there are simple empirical relations to estimate how much lower the velocity is (probably as a function of inner pipe...

Thanks for the input, guys. Believe it or not, I found an expression for turbulent velocity profiles in concentric annuli; It's a modified version of the Karman-Prandtl universal logarithmic velocity distribuation for pipes. For anyone who's interested, it's in the new (2nd) edition of...

Thanks Desertfox, you've confirmed what I've suspected! Atholl

Hi all, I've done some Computational Fluid Dynamic(CFD) simulations of turbulent flow of a Newtonian fluid in a concentric annulus. I want to compare the results in terms of velocity distribution with explicit analytical predictions. I know there are numerous analytic expressions for the...
