摘　　要：采用RNGk-e模型对旋转横流管式微滤膜器流场进行了数值模拟,得出了膜器环隙内流场分布规律。与激光粒子成像测速系统PIV实测结果进行了比较,并以Delphi及Access2000作为软件开发工具,研制了高精度的计算机控制的在线膜器环隙压力测试系统。实测了旋转横流膜器环隙内的压力分布规律,模拟计算结果与实验数据吻合较好。RNG k-e turbulent model was adopted to simulate the rotary cross-flow flow field of a tubular micro-filtration membrane separator numerically. The distribution laws of the flow field in the tubular micro-filtration membrane separator annular gap were obtained. An on-line pressure measuring system for the annular gap of a tubular membrane separator was developed. This system has high precision by using advanced software developing tools, such as Delphi and Access 2000. Using the system pressure profiles in the annular gap of the tubular membrane separator with rotary cross-flow were measured and they agree well with the pressure profiles obtained by the numerical simulating. Also the rotary cross-flow flow field of the annular gap calculated by the numerical simulating was compared with the experimental data measured by PIV system of laser particle image, their coincidence is also satisfactory.
