Abstract

The paper presents RANS computations for the optimization of endplate propellers. Systematic variations of the endplate geometry are made in order to assess the impact of different shapes on propeller performance. Several types of modifications including variations in plate contraction angle, in plate swept and flap angle are studied. 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. Comparisons are made at full scale. Scale effects on fully turbulent flow are also quantified
