- Abstract
- A Boundary Element Method (BEM) hydrodynamics combined with a flow-alignment technique to evaluate blades shed
vorticity is presented and applied to a marine propeller in open water. Potentialities and drawbacks of this approach in capturing
propeller performance, slipstream velocities, blade pressure distribution and pressure disturbance in the flow-field are highlighted by
comparisons with available experiments and RANSE results. In particular, correlations between the shape of the convected vortex-
sheet and the accuracy of BEM results are discussed throughout the paper. To this aim, the analysis of propeller thrust and torque is
the starting point towards a detailed discussion on the capability of a 3-D free-wake BEM hydrodynamic approach to describe the
local features of the flow-field behind the propeller disk, in view of applications to propulsive configurations where the shed wake
plays a dominant role. (literal)
