Abstract
The paper discloses the study of flow crisis in the Ranque—Hilsch vortex tube with a square channel. Previous studies have found the conditions for developing the hydraulic crisis for air flow in this type of tube. The crisis phenomenon is related to the event when the longitudinal velocity at the nearwall vortex-circulation zone interface approaches the value of velocity for spreading centrifugal waves along this boundary. The paper presents and discusses the new detailed results in measuring the kinematic parameters of the crisis flow, including the parameter of velocity pulsation. The evidence of a hydraulic jump near the exit of the swirl flow to the tube working channel.
