PROPELLER BLADE DESIGN INCLUDING SHEAR FLOW INTERACTION

A procedure for designing propellers operating in a shear flow is presented. A vortex lattice method lifting surface code and an axisymmetric incompressible Navier-Stokes (RANS) code have been interactively coupled to compute the blade shape of wake-adapted propellers. The propeller is represented in the RANS calculation by distributions of circumferential mean body forces applied within the swept outline of the propeller. The application of the circumferential mean body force model is investigated by computing the effective inflow for a two-bladed propeller operating in an inviscid inflow. The results demonstrate that the new model properly calculates the effective inflow and swirl left in the wake of the propeller. Additional results are presented for a typical propeller operating in the wake of a tapered afterbody for two loading conditions.
