- Abstract:
- Detailed investigation of flow fields associated with sonic Venturi nozzles with extremely small Reynolds numbers used for flow metering was carried out. The range of Reynolds numbers considered in this work extended from Re = 323 to Re = 452. In the experimental part, global parameters such as discharge coefficient Cd were investigated independently for two different diameters, d = 25 µm and d = 35 µm. Both discovered flow phenomena that were not explainable using simple linear theories. Therefore, in the numerical part of the present investigation, the corresponding flow fields were simulated using compressible viscous flow solvers ACHIEVE and Fluent. The qualitative agreement of the numerical and experimental results was satisfactory; the comparison enabled the authors to explain most of the physical phenomena observed.
