Abstract

The abrasive water-jet (AWJ) erosion process involves the complex interaction between fluid medium, abrasive particles and solid material, which brings great challenges to the establishment of numerical model. Because traditional grid-based methods are not suitable for the problems of local deformation and material removal, the meshfree method smoothed particle hydrodynamics (SPH), based on the unresolved coupling and the discrete element method (DEM), is adopted to establish the model for AWJ study. The fluid medium is treated as a weakly compressible viscous liquid, the solid material is treated as an elastic-plastic material, and the abrasives are treated as rigid bodies. The fluid and solid phases are discretized with SPH particles, and the abrasives are described with DEM particles. The Johnson-Cook (J-C) and Johnson-Holmquist-II (JH-2) constitutive models are used to describe the stress-strain behavior of ductile and brittle materials, respectively. The effectiveness of the numerical model is further verified by AWJ impact experiments. The plastic deformation and cumulative failure characteristics of ductile materials, and the crack formation and propagation characteristics of brittle materials are systematically analyzed. The results provide insight for the AWJ research and lay a foundation for investigation of other complex fluid-particle flow in a numerical way.

摘要

磨料水射流（AWJ）冲蚀过程涉及流体介质、磨料颗粒和固体材料之间的复杂相互作用，这给数值模型的建立带来了巨大挑战。由于传统的基于网格的方法不适用于局部变形和材料去除问题，因此采用基于无网格法的光滑粒子流体动力学（SPH），结合离散单元法（DEM），建立用于AWJ研究的模型。将流体介质视为弱可压缩粘性液体，将固体材料视为弹塑性材料，将磨料视为刚体。流体相和固相用SPH粒子离散化，磨料用DEM粒子描述。分别采用Johnson-Cook（J-C）和Johnson-Holmquist-II（JH-2）本构模型来描述韧性材料和脆性材料的应力-应变行为。通过AWJ冲击实验进一步验证了数值模型的有效性。系统地分析了韧性材料的塑性变形和累积破坏特性，以及脆性材料的裂纹形成和扩展特性。研究结果为AWJ研究提供了思路，并为以数值方式研究其他复杂的流体-颗粒流动奠定了基础。
