%X A second order cell-centered NND finite volume algorithm on unstructured triangular grids is presented for solving the Euler equations.A self-adaptive mesh technique is employed to improve the efficiency of the calculation.Two examples,shock reflection from a wall and flow in ZD wind tunnel with a step,are solved, and the results show that the present algorithm possesses good stability characteristics and capability of capturing the shock waves.
