The reasons to introduce a new definition of the effective mean velocity in model propulsion tests PART II

Abstract

The essence of the effective mean velocity definition is analysed by the author. This definition is indivisibly connected with the effective velocity field being in interaction with the ship screw propeller. The effective mean velocity is set against the mean value of the isolated effective velocity field. The differences in the relations between criterional quantities in the averaging process in both cases are specified. These differences make the necessity of introducing a new effective mean velocity definition to the model propulsion tests and to the numerical simulation procedures well justified.
