Effect of Freestream Radial Velocity Component on Hydrodynamic Analysis of Propellers.

Abstract

For wake fields with circumferential averages that include a small radial component, an additional term arises in the mathematical model used for design or performance prediction of propellers that has been previously overlooked. This term arises from the boundary condition that the blade is impenetrable and is a function of only geometry and the inflow radial velocity component. This simple additional term is shown to be important for the example considered, leading to a variable change in camber and a pitch reduction. (Author)
