This paper reviews the literature on Ranque–Hilsch vortex tube experiments using air as the
working fluid. This is a simple device without any moving parts that uses vortex motion to …

A vortex tube is a very simplistic device capable of producing phenomenal temperature
separation effect. Due to spontaneity of this effect coupled with diversified applications …

The generation of cold and hot streams from a single injection in a vortex tube has been
investigated by many researchers, aiming to define the primary reasons for the separation …

Energy separation procedure of vortex tube can be improved by using truncated cone
throttle valve. Experiments are performed to study the effect of the geometrical parameters …

Although many efforts have been made to disclose the energy separation phenomenon
based on theoretical, numerical and experimental analysis in vortex tubes, it is still difficult to …

A vortex tube is a mechanical device which provides instant heating and cooling by
separating the hot and cold streams via application of compressed working fluid to the orifice …

Abstract The Ranque–Hilsch vortex tube is a simple device with no moving parts and no
mechanical operations. This device separates the inlet air into two distinctive regions; an …

Various methods had been taken for the flow field studies, among them, qualitative
visualizations and probe intrusive measurements have a long history and had been adopted …

In this article, the development of the energy separation for the vortex tube has been briefly
reviewed. This review mainly focuses on three aspects, they are the energy separation …

The present paper reports an investigation of a double-circuit Ranque-Hilsch vortex tube
using a fully three-dimensional numerical model of the turbulent compressible air flow. The …
