Purpose. On the basis of the numerical decision of the Reynolds equations verification of mathematical modeling of vortex valves and vortex chamber superchargers in a mode of the closed exit channel when distributions of pressure along radius of these two devices are similar is conducted. Approach. Verification is made by comparison with results of experimental researches on integrated parameters: pressure upon an exit from the device, the flow rate in the supply channel, the flow rate, which is sucked up in the device from environment. Findings. It is as a result received that the most suitable model is the model of an incompressible fluid with rotation-curvature correction on the basis of SST turbulence model. This model provides the least error at vacuum calculation on an axis of a rotating stream is not dependent on device geometry. Also comparison on kinematics parameters on the basis of static pressure comparison on the top end cover of the vortex chamber was made. More exact results are received for the vortex device with radial diffuser.References
