ALE approach for modeling of inviscid compressible fluid flow

This paper is devoted to numerical solution of inviscid compressible fluid flow in domains with moving boundaries. Non–linear system of Euler equations in ALE formulation was solved by computational software which was developed in Matlab environment. The spatial discretization of this system was accomplished by finite volume method adapted for triangular computational grids and inviscid fluxes were discretized by Van Leer flux splitting scheme with linear reconstruction and Barth’s limiter. The algorithm for the deformation of computational grid and boundary conditions are described. Numerical results of the computational software were validated using the well - known case of inviscid fluid flow around vibrating aerofoil NACA 0012 which was experimentally investigated by AGARD group.
