CFD-predicted and PIV-measured data were compared along dimensionless radial
coordinates (0.5–1.0 r/R) at an axial position of h/H L ¼ 0.1. The comparison of the
velocity components in the SP100 revealed only minor differences for v
! (up to
7.5%) and w
! (up to 8.7%). However, the CFD velocity profiles were well captured,
and the overall agreement of PIV and CFD was satisfactory, with findings consistent
with those of Kaiser et al. [50]. A comparison of the fluid velocities in the SP100 was
