SINOPSIS

This work deals with the study of the gas phase effect on integral characteristics of a swirling two-phase flow with a precessing vortex core. The formation conditions of a precessing vortex filament were modeled in hydrodynamic vortex chambers with a sudden expansion, where the flow was swirled by means of the vane and tangential swirlers. Experimental dependences of the frequency of vortex core precession and total pressure drop in the vortex chambers on gas content are obtained for different degrees of flow swirl. The studies have shown that the main effect of air supply on the flow parameters is associated with separation of the lighter gas phase toward the vortex core center and formation of a gas core along the vortex axis. The effective separation of air from liquid into the gas core is particularly confirmed by the fact that the measured data are well generalized in dimensionless variables based on the liquid phase parameters.
