摘　　要：基于workbench平台,应用Fluent软件对净水机UVC杀菌装置内部流场进行数值仿真分析。以25℃液态水为流体介质,基于标准壁面函数法和旋流修正RNG k-ε湍流模型,分析装置不同进出水孔内径、分水孔内径和分水孔数量4个维度下内部流速、压力、迹线等变化特点和不同参数组合对流动特性的影响规律,为进一步优化产品结构及提高杀菌性能给出设计方向和理论参考依据。Based on the workbench platform,the internal flow field of UVC sterilization device is simulated and analyzed by using Fluent software.With 25℃liquid water as the fluid medium,standard wall function method and RNG K-εTurbulence model is used to analyze the changing characteristics of internal flow velocity,pressure,trace,etc.and the influence of different parameter combinations on flow characteristics under the four dimensions of different inlet and outlet hole diameters,and outlet hole numbers of the device,so as to provide design direction and theoretical reference for further optimizing product structure and improving sterilization performance.
