摘　　要：针对平面式和直纹曲面的电喷镀阳极喷嘴流场设计,以电镀液的流道为物理模型建立了相应的数值模型,应用计算流体力学方法对流场的数值模型进行求解应用。单相流模拟喷嘴内液体流动情况,VOF多相流模型模拟分析喷射液柱与空气混合状态,研究工件表面镀液分布情况。根据仿真结果,并结合试验,确定最优的阳极喷嘴设计结构。To design the flow field of inner -anode nozzle in electric plating on flat and ruled surfaces, a numerical model was built according to the physical model of the electrolyte flow channel, and the computational fluid dynamics （CFD） method was applied to solve the numerical model. Using single-phase model simulates the flow condition based on the anode geometry model. VOF model is used to simulate the interface between two-phase （ gas and liquid） and the liquid distribution on workpiece. The optimization design of anode nozzle is determined by the results of simulation and experiments.
