| Résumé | Numerical investigations were performed to predict effects of propeller hub taper angle and pod geometry configurations on propulsive performance. An existing time domain panel method code was extended to handle the simulation tasks. The effect of taper angle was examined in terms of shaft thrust coefficient, KT, and torque coefficient, KQ, for different taper angles of -15° (pull/tractor configuration) and +15° (push configuration). The predicted pressure distribution was also analyzed to investigate the effect of taper ratio on pressure coefficient, Cp, at the blade root section. The effects of pod-strut geometry on KT and KQ of a propeller with taper angles of 15° and 20° with two pods both in push configuration were examined. A complementary experimental study of the effects of taper angle on propulsive performance was also conducted for 15° and 20° taper angles in push configuration. Numerical predictions and experimental measurement showed a good agreement over a wide range of advance coefficients from the bollard pull condition to the design advance coefficient of about 1.0. |
