Mô phỏng số ứng xử của tấm bê tông dưới tác động của tia nước tốc độ cao

The high-pressure water jet technology has been widely applied in the construction industry. However, understanding the complicated interactions between high-velocity water jets and concrete surfaces remains a significant challenge. This paper employs a numerical simulation method using the Coupled Eulerian-Lagrangian (CEL) technique to analyze the behavior of concrete slabs under the impact of high-velocity water jets. The study focuses on the pressure distribution at the impact zone and the deformation characteristics of concrete under water jet velocities ranging from 100 m/s to 1000 m/s. The results indicate that the maximum pressure at the impact zone ranges from 0.13 GPa to 1.6 GPa, concentrated at the center and gradually decreasing outward. The findings provide critical data for practical applications in the concrete structures subjected to high-velocity water jet impacts.
