摘要：
Complete Navier-Stokes equations are solved numerically for the case of an intense swirling flow in an axisymmetric channel with an orifice plate in the delivery cross section and a throttle in the form of a peripheral slit at the opposite end. Flow patterns and velocity and temperature fields are obtained. The presence of precession of axial vortex is observed, as well as the formation of large-scale vortex structures. The numerical calculation results are compared for the first time with the experimental data obtained using Ranque-Hilsch energy separators.
