results to corroborate the reliability of the numerical
predictions, using two sets of experimental data
comprising predictions by the inviscid flow code RAPID
and the viscous flow code PARNASSOS.
The PARNASSOS results compared quite well with
the experiments, suggesting that CFD can give a detailed
picture of the flow in the vicinity of a strut, provided that
free surface deformation, sinkage, and trim are taken
into account. It can also give guidance in the twisting
of the strut, or in choosing a proper mean orientation
angle.
A claimed advantage of using CFD is that information
on the complete flow field is obtained. This is said to
