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.
