A NEW METHOD OF EFFECTIVE MEAN VELOCITY DETERMINATION IN MODEL PROPULSION TEST

The effective mean velocity determination from numerical simulation according to the effective mean velocity definition in common use described. The relationship between the effective mean velocity from calculations and from model tests is presented. This numerical simulation method is applied to determine the effective mean velocity according to a new proposed definition of the effective mean velocity. The resulting mean values are independent of the averaging criterion used: the thrust identity, the torque identity or the lower power identity. The relationship between the effective mean velocities from both definitions are given.
