Comparison of Test Data and CFD
The mean velocity field is determined by time averaging over five complete runner
revolutions for the hybrid models and eight complete runner revolutions for the URANS
models to filter out all unsteadiness.
The survey axes, \textit{S*}, at sections W0-W2 (see Fig. \ref{Test_rig}), are normalized
by the throat radius, $R_{throat}$=0.05m, and the velocity is normalized by the bulk
velocity at the throat, $W_{throat}$.
The axial axis is downward and the runner rotates in the positive direction according to
the right-hand rule.
