Abstract :
Based on Reynolds-averaged Navier-Stokes equations, the three-dimension solid model, three-dimension model without supporting frame and two-dimension model of orifice rotameter were computed using computational fluid dynamics (CFD) method. The numerical computational results and experiment data were compared and analyzed in detail. It can be learned from analysis that the full-scale error of two-dimension model is the smallest among the above three models. The two-dimension model can increase the calculation precision and efficiency. And the pressure contour was in good agreement with the actual basin. In short, two-dimension model is the most convenient and efficient simulation model of the three models.
