Dynamics of the End-Face Boundary Layer and Hydraulic Resistance of a Vortex Chamber with a Side Swirler

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

The results of experimental and numerical investigations of the effect exerted by air flow rate and flow twist angle on the dynamics of an end-face boundary layer in a diaphragmed vortex chamber with a multislit lateral swirler are presented. Data on the hydraulic resistance of the chamber have been obtained. It is shown that gas injection through the slits of the lateral swirler leads to the formation of flow in the chamber of the same structure as that formed as a result of the injection uniformly distributed over the side wall with a smaller twist angle if the static pressure losses in the chamber in both cases are equal. Generalization of the dependence of the hydraulic resistance of the chamber on the effective flow twist angle is obtained for the investigated range of Reynolds numbers.
