Abstract
LDV phase sampling technique is developed and adopted f or the analysis of the flow upstream and behind a four blade, highly skewed installed propeller, for the case of a twin screw ship model in a large circulating water channel. The implemented technique allows the reconstruction of the 3D flow field for each revolution angle in transversal planes located as close as possible to the blade trailing and leading edge. The main features of the propeller installation are highlighted as well as the strong and complex interaction of the propeller with the hull wake, especially in the brackets regionFile in questo prodotto:
