International audience; The noise radiated at the inlet of turbo-fan engines corresponds to a significant noise source at aircraft level, which is generally controlled by acoustic treatments (liners) applied on the engine and the nacelle. For cost an

An algebraic Newton-multigrid method is proposed in order to efficiently solve systems of nonlinear reaction-diffusion problems with stochastic coefficients. These problems model the conversion of starch into sugars in growing apples. The stochastic

Publikováno v: Digests of the 2010 14th Biennial IEEE Conference on Electromagnetic Field Computation.

This paper addresses what the influence of uncertainty on ferromagnetic material properties is on the torque yielded by ferromagnetic cylinders rotating at high speeds. To that end, two state-of-the-art high-order stochastic solution approaches, the

Nonlinear Stochastic Galerkin and Collocation Methods: Application to a Ferromagnetic Cylinder Rotating at High Speed

Autor: Eveline Rosseel, Stefan Vandewalle, Herbert De Gersem

Publikováno v: Communications in Computational Physics.

The stochastic Galerkin and stochastic collocation method are two state-of-the-art methods for solving partial differential equations (PDE) containing random coefficients. While the latter method, which is based on sampling, can straightforwardly be
