The subject of present study is the application of mesh free Lagrangian two-dimensional non-cohesive sediment transport model applied to a two-phase flow over an initially trapezoidal-shaped sediment embankment. The governing equations of the present model are the Navier-Stocks equations solved using Weakly Compressible Smoothed Particle Hydrodynamics (WCSPH) method. To simulate the movement of sediment particles, the model considers a powerful two-part technique; when the sediment phase has rigid behavior, only the force term due to shear stress in the Navier-Stokes equations is used for simulation of sediment particles’ movement. Otherwise, all the Navier-Stokes force terms are used for transport simulation of sediment particles. In the present model, the interactions between different phases are calculated automatically, even with considerable difference between the density and viscosity of phases. Validation of the model is performed using simulation of available laboratory experiments, and the comparison between computational results and experimental data shows that the model generally predicts well the flow propagation over movable beds, the induced sediment transport and bed changes, and temporal evolution of embankment breaching.

针对地下车库、空调出风口等存在高速气流的特殊场所,利用火灾探测综合模拟实验平台,根据气流是否影响烟颗粒生成过程,分别设计2种实验方案,分析比较了光电型与离子型两种感烟火灾探测器在不同气流条件下的响应灵敏度。实验结果表明,在烟颗粒生成过程不受气流影响的情况下,两种感烟探测器的响应灵敏度均随气流速度增大而下降。在气流影响烟颗粒生成过程的情况下,光电感烟探测器的灵敏度依然随着气流速度的增大而迅速下降;而离子型感烟探测器的灵敏度受气流速度影响较小,在高速气流条件下依然保持较高的灵敏度。综合分析表明,离子感烟探测器较适合在高速气流环境中工作。
