حل معادله دايمي اويلر در يك شيپوره دوبعدي در رژيم هاي مادون صوت ، گذر و مافوق صورت

In this paper, the steady state solution of two-dimensional Euler equations in a nozzle in subsonic, transonic and supersonic regimes is considered. The solution is based on Jamesonʹs finite volume method. This method uses central difference discretization in space with an intelligent artificial dissipation and a four-stage Runge-Kulta scheme for advancing in time. The rate of convergence, local time step and the amount of the artificial dissipation coefficients In one and two dimensional for internal and external flows are the goals of this study.
