An inviscid actuator disk model is embedded in a three-dimensional low-order panel method code for inviscid incompressible ow in order to study the propeller effects on an arbitrary body. The actuator disk model predicts the time-averaged induced velocities in the slipstream of a propeller with an arbitrary radial distribution of load. The model is constructed by superposition of four vorticity distributions, by neglecting the radial contraction of the vortex tube and assuming a fixed wake for the propeller. Experimental data, available from the licterature, have been used to validate the actuator disk model embedded in the panel method code.

Abstract
An inviscid actuator disk model is embedded in a three-dimensional low-order panel method code for inviscid incompressible ow in order to study the propeller effects on an arbitrary body. The actuator disk model predicts the time-averaged induced velocities in the slipstream of a propeller with an arbitrary radial distribution of load. The model is constructed by superposition of four vorticity distributions, by neglecting the radial contraction of the vortex tube and assuming a fixed wake for the propeller. Experimental data, available from the licterature, have been used to validate the actuator disk model embedded in the panel method code.File | Dimensione | Formato | |
