Abstract
A phase sampling technique on random data acquired with LDV is
developed to investigate the flow upstream and downstream a five blade
installed propeller on a single screw ship model in a large circulating water
channel. The technique allows the reconstruction of the 3D flow field for
each angle of revolution along transverse planes located as close as possible
to the blade trailing and leading edges. The main features of the propeller
flow field are highlighted as well as the strong and complex interactions
between the propeller itself and the hull wake.
1 Introduction
The accurate analysis and knowledge of the propeller flow field in a non
uniform inflow has a fundamental role in the naval field due to the fact
that the propeller j
