Case: PCH23 Title: Fully Developed Rotating Channel Flow Experiment (Nakabayashi & Kitoh) File: PCH23/param.dat Description: This file contains various parameters and constants for the several flows making up PCH23. The data is organized by Reynolds number (Re_b), and is listed for each rotation rate given by R_Omega = 4delta^2|Omega|/nu, and for each side (P for pressure, S for suction). The files for each Reynolds number are named for the R_Omega (ro07 for R_Omega=70). Given are the friction factor Cf, the ratio of the friction velocity (u*=u_tau) to that with no rotation, the same for Cf, the log-law intercept (C1) and karman constant (k) and the van Driest damping factor Ar+.
