DIRECT NUMERICAL SIMULATION STUDY ON RELATIONSHIP BETWEEN RANQUE-HILSCH EFFECT AND TURBULENCE IN HIGH-SPEED SWIRLING FLOW INSIDE A CYLINDRICAL VORTEX CHAMBER

Direct numerical simulation study on relationship between Ranque-Hilsch effect and turbulence in high-speed swirling flow inside a cylindrical vortex chamber

The Ranque-Hilsch vortex tube (RHVT) is a device which can separate compressed gas into high and low energy flows only through its own fluid motion by generating a high-speed swirling flow inside a cylindrical vortex chamber.The energy separation phenomenon of RHVT is called the Ranque-Hilsch effect (RH effect).Although numerous studies have been c

Animals Do Not Induce or Reduce Attentional Blinking, But They Are Reported More Accurately in a Rapid Serial Visual Presentation Task

Evolutionary psychologists have suggested that modern humans have evolved to automatically direct their attention toward animal stimuli.Although this suggestion has found support in several attentional paradigms, it is not without controversy.Recently, a study employing methods customary to studying the attentional blink has shown inconclusive supp
