摘要: 采用激光驱动技术模拟高速运动金属颗粒与气体相互作用过程，研究高速气固两相流输运过程。采用驱动靶优化设计、激光参数调节等方法对颗粒加速过程进行控制，利用高时空分辨率、高精度瞬态实验诊断技术获取高速颗粒瞬态物理图像。通过求解三维雷诺平均Navier-Stokes方程和刚体飞行六自由度动力学方程数值模拟高速单颗粒与气体混合过程，方程采用高斯−赛德尔隐式方法进行时间推进求解。研究表明，激光驱动方法能够有效地发射金属颗粒，阴影照相技术能够有效获取高速颗粒物理图像。数值模拟给出了高速颗粒与气体作用的流场参数。Abstract: We apply laser-driven launching technique to the interaction between high-velocity metal granule and gas to investigate high speed gas-solid two-phase flow transport. Optimization of target design and adjustment of laser parameters were used to control the laser-driven process. Diagnostic tools with high resolving power of space and time as well as higt accuracy were set up to capture the high-velocity granule. The unsteady flow field of the granule was simulated by solving the the 3-D Reynolds averaged Navier-Stokes equations and six degree of freedom ballistic equation. With the implicit Gauss-Seidel scheme, the code was advanced in time. The results indicated that the laser-driven launching technique was effective and the shadow photographs of high-velocity granule were taken successfully. The aerodynamic drag of high-velocity granule was computed with numerical simulation.
