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 Gameboy Charger 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 stu

Ear replanatation: a case report and literature review

Background: Total ear amputation is a rare accident.The most common causes are traffic accidents (33 %), followed by fights (28 %).In 1980, Wine Glasses Pennington et al.reported the first successful microsurgical ear replantation in a 29-year old man.Methods: An English literature review of trauma cases of total ear amputation showed only 13 succe

Recent Advances in Chirally-Coupled Core Fibers

To meet the needs of high-power fiber Teethers lasers, a new fiber structure called chirally coupled core (CCC) fiber has attracted the attention of researchers all over the world.CCC fiber consists of two cores, one of which is a central core distributed along the axial direction, and the other is a side core that is offset from the central axis a
