Abstract
VTT Technical Research Centre of Finland and Aalto
University have been investigating the numerical
simulation of cavitating propellers. Special emphasis is
placed on having a reasonable grid resolution in the tip
vortex and at the blade wake locations in the slipstream.
The calculations are performed with a uniform inflow.
The propeller analyzed in this paper is the model size
PPTC propeller of SVA Potsdam. The effect of the
experimental coefficients in Merkle's mass transfer model
on the cavitating tip vortex is studied systematically.
The paper contains calculations with different grid
resolutions to show that a reasonable grid convergence of
the results is reached. The calculations are conducted
with FINFLO, a general-purpose CFD code. The numerical
results are compared with model test results. The model
test results contained the Laser Doppler Velocimetry
(LDV) measurements of the propeller wake field in wetted
conditions and the cavitation observations. The numerical
results and the experiments show a reasonable correlation
with each others
