Abstract
- Scattering from propellers is investigated using the 3D Finite Element Method (FEM), alongside a simpler integral equation (IE) method using 1D discretization. It is shown that under certain conditions and near the propellers' resonant frequency, results using the two methods are in agreement, justifying the use of the IE method; this is advantageous because of smaller computation times, and for providing a physical insight to the scattering phenomena at hand. Anechoic chamber measurements are performed to validate the numerical results. [ABSTRACT FROM AUTHOR]
