Essay On Vortex Tube

Abstract— Vortex tube is a simple device with no moving parts. It separates inlet high pressure stream of air into two lower pressure streams of cooler temperature at one end and hotter temperature at other end. It is basically of counter flow type and parallel flow type. It has many advantages and wide range of applications, mostly using counter flow owing to better performance than parallel flow. Most of the applications reflect the benefits in terms of performance, energy, compactness or as an alternative to the conventional method. Few applications are highlighted in this paper. Variable temperature system uses vortex tube along with liquid nitrogen cooled heat exchanger to maintain lower temperature as the biochemical samples are prone to change properties in unconditioned environment. In case of high

Common advantages of machining incorporating cryogenic cooling are retaining of workpiece material properties, cutting temperature according to cooling approach, tool wear reduction and increase in tool life, workpiece surface roughness improved, lower tool/ workpiece friction ratio and cutting forces were affected.

5. INDUSTRIAL APPLICATION OF MULTI-PURPOSE VOR-TEX AIR COOLERS [4]:

The temperature distribution of the high-speed turbulent flow of air (gas) in the field of centrifugal forces is used on an increasing scale in industry. The first generation of multi-purpose vortex air coolers was produced commercially in the former USSR to ensure availability of vortex refrigerators in any area of the plant.

The industrial verification of first generation vortex coolers was needed:

• obtain practical technological information on the technological and service properties of vortex refrigeration technology;

• select preferred design for development and new generation efficient coolers;

• compare vortex coolers with "conventional" system air
