Abstract :
The main aim of the current paper is to propose an upwind local
radial basis functions-finite difference (RBF-FD) method for
solving compressible Euler equation. The mathematical formulation
of chemically reacting, inviscid, unsteady flows with species
conservation equations and finite-rate chemistry is studied. The
presented technique is based on the developed idea in [58]. For
checking the ability of the new procedure, the compressible Euler
equation is solved. This equation has been classified in category of
system of advection-diffusion equations. The solutions of advection
equations have some shock, thus, special numerical methods should
be applied for example discontinuous Galerkin and finite volume
methods. Moreover, two problems are given that show the
acceptable accuracy and efficiency of the proposed scheme.
