摘要
针对电解车削加工的流场设计,基于内喷式阴极结构和电解液流道的物理模型建立了相应的数值模型,应用计算流体力学方法进行求解,得到了流场的速度和压力分布。根据求解结果,分析了阴极内部结构对流场的影响;通过改进阴极的内部结构,得到了相对较好的模拟结果;结合工艺试验,验证了数值模拟的准确性,表明可将计算流体动力学的方法用于流场的模拟和指导阴极结构的改进设计。
To design the flow field in electrochemical turning（ ECT）,the numerical model was established based on the structure of the inner-spraying cathode and the physical model of the flow channel. The computational fluid dynamics（ CFD） method was applied to solve the numerical model and the distributions of the velocity and pressure were obtained. The influences of the cathode internal structure on the flow field were analyzed according to the numerical simulation results. The better simulation results were obtained by means of the optimization of the cathode internal structure. Based on the experiment,the accuracy of numerical simulation results was verified. It is indicated that the CFD method can be applied to simulate the flow field and guide the optimization of the cathode internal structure.
