Original Abstract

Meshfree Finite point method (FPM) has been used for the solution of sound (noise) propagation, which can be modeled by linearized Euler equations (LEE). Important property of a numerical method for simulation of sound propagation is the capability to reach the high order of accuracy. In this paper we present the accuracy improvements of FPM using the reconstruction of variables in the Riemann solver by Taylor polynomial. Order of the derived meshfree method will be verified on 2D Acoustic pulse problem which serves as a benchmark problem with known analytical solution.
