| 摘 要： | 从积分形式的非定常Euler方程出发,在固联于振动冀型的贴体坐标系下,采用有限体积法进行离散,并根据对称型TVD格式构造相应的数值通量,数值模拟了振动翼型的非定常跨音速绕流的变化过程。计算结果表明,该方法能较好地捕捉流场中的运动激波,准确地定出激波位置与强度;并且易于推广到求解任意振动方式的跨音速非定常绕流问题。

| Abstract: | Transonic flow over an oscillating airfoil has been computed by solving the Euler equations. A finite volume scheme is used to spatially discretize the integral form of the Euler equations for a moving domain, and a symmetric TVD scheme is presented to construct dissipative terms. The method may robustly and accurately capture moving shock waves in flowfield. Furthermore, the computing technique allows a very neat extension to the treatment of arbitrary movement and deformation of the mesh. |
