On the basis of current knowledge covering a wide range of vortex devices, the methodology of model tests was developed (in pilot-plant scale) for liquid flow in vortex regulators. The paper presents selected investigation results related to the influence of geometric parameters: d out /d in , h c /d in , D/d in , R o /d in and constant K, as well as operational parameters, such as an air core diameter (d a) and a spray cone angle (γ), on liquid flow throttling characteristics for cylindrical

The empirical formulae developed allow for a rational selection of geometrical parameters for such regulators that can be used in environmental engineering which was demonstrated in the example.
