Abstract
Systematic variations of the endplate geometry for two
end-plate propellers are made in order to assess the
impact of the blade tip shape on propeller performance.
Several types of modifications are analyzed including
variations in plate width, contraction angle, plate
sweep, and flap angle. The effect of end-plate geometry
modifications in the radial distribution of circulation
is illustrated. The magnitude of the circulation is
derived from the analysis of the tangential velocities
behind the propeller. The contribution of pressure and
friction components to the total endplate forces is also
shown. Comparisons are made at full scale. A special
procedure for the generation of the computational grids
is implemented in order to minimize computational errors
in the comparison of the alternative geometries. RANS
code FINFLO is used in the evaluation
