Improvement of surface finish and material removal has been quite a challenge in a finishing operation such as abrasive flow machining (AFM). Factors that affect the surface finish and material removal are media viscosity, extrusion pressure, piston velocity, and particle size in abrasive flow machining process. Performing experiments for all the parameters and accurately obtaining an optimized parameter in a short time are difficult to accomplish because the operation requires a precise finish. Computational fluid dynamics (CFD) simulation was employed to accurately determine optimum parameters. In the current work, a 2D model was designed, and the flow analysis, force calculation, and material removal prediction were performed and compared with the available experimental data. Another 3D model for a swaging die finishing using AFM was simulated at different viscosities of the media to study the effects on the controlling parameters. A CFD simulation was performed by using commercially available ANSYS FLUENT. Two phases were considered for the flow analysis, and multiphase mixture model was taken into account. The fluid was considered to be a Newtonian fluid and the flow laminar with no wall slip.

为了实现蓄滞洪区内各洼淀实时洪水调度,考虑到蓄滞洪区内复杂河网与洼淀交错的情况,建立了河道、滞洪区联合计算的一、二维衔接洪水演进数学模型,在考虑铁路、公路、堤防及桥涵等阻水建筑物等复杂边界条件下,采用有限体积法进行离散和求解。结合蓄滞洪区实时洪水调度仿真系统的总体框架,建立了模拟洪水在蓄滞洪区内任意位置的水位、流速、淹没水深、历时等演进过程的一、二维洪水演进数值仿真系统。结合大清河实测资料对东淀滞洪区洪水演进进行了模型验证,结果基本吻合,并应用该系统对大清河滞洪区五洼联合调度方案进行了实时模拟,分析了洼淀联合调度下出现的倒淀现象,对不同方案进行了比较分析,实现了实时的洪水调度分析。
