摘　　要：基于计算流体力学开源软件OpenFOAM的双流体模型及相应求解器,模拟研究了激波作用下颗粒层的动态演化特性,并通过与文献报道的实验结果对比,评估了数值模拟结果的定量准确性。对比发现模拟得到颗粒层上下游压力变化以及颗粒层自由面位置的时间演化都能与实验结果定量吻合。该研究结果为下一步基于OpenFOAM软件开展冲击作用下颗粒抛洒特性的数值模拟奠定了基础。The dynamic evolution of particle cloud subject to the shock wave was numerically investigated using the two-fluid model(TFM)and the corresponding TFM solver available in the Computational Fluid Dynamics(CFD)open-source platform OpenFOAM.The quantitative accuracy of the simulation results was evaluated by comparing with the experimental results reported in literature.It was found that the predicted evolutions of the upstream and downstream pressures and also the positions of the free surfaces of the particle cloud were all in good agreement with the experimental results.This work thus laid a solid foundation for the future research on the numerical modeling of shock-driven dispersion of particles basing on the OpenFOAM platform.
