摘要 为了获得冲压加速器内高速流场与弹丸周围激波结构的特性,采用高精度WENO计算格式求解二维可压欧拉方程,结合自适应网格加密技术(AMR)与沉浸边界法(IBM),数值模拟了冲压加速器冷态实验.结果表明,计算方法很好地描述了冲压加速器内部流场和激波结构,完整地呈现了弹丸周围激波的形成与发展过程及相关参数的变化情况,可以对冲压加速器冷态实验给予一定的指导与借鉴. To obtain the characteristics of supersonic flow-field and shock wave structure around projectile inside ram accelerator,the two-dimensional compressible Euler equation was solved by using high-order Weighted Essentially Non-Oscillatory(WENO) scheme.By combining Adaptive Mesh Refinement(AMR) technique and Immersed Boundary Method(IBM),the experiment in ram accelerator under the cold shot condition was numerically simulated.The result shows that the flow structure and shock wave structure inside ram accelerator under the cold shot condition can be shown clearly.The simulation results agree well with corresponding experimental results.The hypersonic flowfield and shock waves inside the ram accelerator were captured.The generation and development of shock waves and relative parameters around the projectile were presented.The study offers reference for the cold launch experiment of ram accelerator.
