Development of a Second-Order Corrector for an Accurate Laplacian Operator in SPH

Wirth, Martin; Chaussonnet, Geoffroy; Koch, Rainer; Bauer, Hans-Jörg

Abstract:
A new numerical method, called Smoothed Particle Hydrodynamics (SPH) is applied in the field of aeroengines. In the last decade, SPH has shown promising advantages such as the natural advection of the phase interface without numerical diffusion, in case of multiphase flows. This makes it a serious alternative to traditional grid-based methods, leading to a numerous number of industrial applications. However, this method suffers from numerical weaknesses. For instance, it is observed that the nominal Laplacian operator, involved in viscosity models, fails to retrieve fi ... mehr
