Résumé : |
In this paper, a second order explicit finite difference scheme has been defined to solve a class of non-homogenous conservation laws, which includes the one-dimensional Euler equations with source terms arising from variation of area along a narrow duct. The basic idea has been the transformation of the system of conservation laws with source terms in a homogenous system. The proposed scheme recognizes stationary solutions of the non-homogenous system. Numerical results are presented to demonstrate the performance of the described scheme. |
