Simulation of the acoustic wave propagation using a meshless method

Abstract

This paper presents numerical simulations of the acoustic wave propagation phenomenon modelled via Linearized Euler equations. A meshless method based on collocation of the strong form of the equation system is adopted. Moreover, the Weighted least squares method is used for local approximation of derivatives as well as stabilization technique in a form of spatial fltering. The accuracy and robustness of the method is examined on several benchmark problems.This paper presents numerical simulations of the acoustic wave propagation phenomenon modelled via Linearized Euler equations.
