Comparison of Periodic Flow Fields in a Radial Pump among CFD, PIV, and LDV Results
Published 2009-01-01“…The comparison of the results shows that PIV and LDV give nearly the same phase-averaged velocity fields, but LDV predicts the turbulence much clearer and better than PIV. CFD underestimates the turbulence level in the whole region compared with PIV and LDV but gives the same trend.…”
