NONLINEAR ACTUATOR DISK THEORY AND FLOW FIELD CALCULATIONS, INCLUDING NONUNIFORM LOADING

The axisymmetric flow induced by an actuator disk with prescribed nonuniform circulation distribution is considered. Coupled, nonlinear, singular integral equations governing the wake geometry and vortex density are developed from the force-free condition and discussed from physical and mathematical points of view. An iterative solution based partly on the method of successive approximations and partly on the Newton-Raphson method is put forward, together with convergent numerical results for illustrative cases, both static and nonstatic. Corresponding detailed flow field calculations are included.
