The purpose of this review paper is to overview of the past
investigations of the design criteria of vortex tubes, to draw together the
mass of literature, and to provide detailed information on the design of vortex
tubes. The vortex tube, also known as the Ranque-Hilsch vortex tube (RHVT), is
a mechanical device that separates compressed air into hot and cold streams
flowing in vortex motion/tangentially into the vortex chamber through inlet
nozzles. This instrument has no moving components, does not break or wear, and
hence requires minimum maintenance. The vortex tube is ideal for a variety of
applications since it is simple, lightweight, quiet, and small, and it does not
need Freon or other refrigerants (HFCs or CFCs). Though the vortex tube is
simple in structure, the internal mechanism of airflow and energy transfer is
very complex. A series of theories have been presented by researchers regarding
the energy flow inside the vortex tube. This paper after a brief introduction
and literature survey, focuses on the design criteria, applications of RHVT and
the results obtained up to now. One of the objectives of this paper is to
highlight the application of this device and its usage in the industry, rough
estimates of temperature that are achieved and which be used in particle
applications. The review will conclude with comments on future directions that
this device can be used and can be applied for further study and investigation.
By reviewing most of the theories, predicting the vortex tube performance and
showing the common features and promising add-ons, this review paper could set
the basis for the development of the first commonly accepted design model of
counter-flow vortex tubes working with perfect gas for spot cooling
application.
