“…(Rafiee & Sadeghiazad, 2014) on number of nozzles and size of nozzles. The findings were similar to that of experimental results, a mix prediction exists, wherein some researchers (Dincer, Tasdemir, Baskaya, & Uysal, 2008;Uluer, Kirmaci, & Atas, 2009;Kocabas, Korkmaz, Sorgucu, & Donmez, 2010;Polat & Kirmaci, 2011;Pourmahmoud, Hassanzadeh, & Moutaby, 2012) have observed drop in performance of energy separation with increase in nozzle number. Some of these (Ameri & Behnia, 2009;Rafiee & Rahimi, 2013) have noticed increase in cooling capacity/energy separation/ performance for converging shape nozzles.…”

Vortex tube is the device that separates pressurized fluid into hot and cold fluid streams simultaneously. The scientific community has done extensive experimental and theoretical studies since invention of vortex tube to augment the performance of the tube by varying geometrical and operational parameters; the paper deals with parametric review of all such work. The review takes into account effect of almost 14 parameters on performance of vortex tube. It includes developments in tube geometry like L/D ratio, number of nozzles; hot end valve angle and cold orifice diameter etc. are discussed along with different fluids and operational parameters like CMF and stagnation point etc. The focus of most of the theoretical and experimental studies was to investigate mechanism of thermal separation and geometry optimization. The main objective of this review is to discuss efforts made in order to enhance the refrigeration effect so that, missing links could help for future research.

“…Since its invention, in 1933 [7], investigations have been carried out to understand the processes involved in a vortex tube. Much of the earlier research in the subject matter has primarily focussed on the separating mechanisms within the tube, including theoretical analysis of the separation process [8,9], optimisation of the tube performance for different applications [10,11], numerical simulations of the temperature separation within the tube [12][13][14][15] and investigation of the internal flow behaviour [1,[16][17][18]. Different understandings of the internal flow mechanisms and explanations for the energy separation within the vortex tube, which have been reviewed and analysed in recent publications [19][20][21][22], imply the lack of general consensus and the requirement of clarification of the complex separating phenomenon.…”

The Expansion Process in a Counter-flow Vortex Tube

The process of temperature separation in a Ranque-Hilsch vortex tube is dependent on a multitude of factors, such as the pressure gradients, flow stagnation and mixture, energy transfer between different flow layers and heat transfer between the tube and the ambient air. The pressure gradient in an expansion process within a vortex tube has been proposed as the dominating reason for the temperature drop. However, at present, there is no general agreement within the research community for the expansion process itself, primarily due to the complexity of the internal flow conditions in the tube. Therefore, in the present article, a deeper insight into the separation mechanism within a vortex tube is presented, based on an analytical analysis using different expansion models, including isentropic expansion, free expansion and Joule-Thomson expansion. It was observed that the isentropic expansion is the only possible expansion process within a vortex tube. This was confirmed through comparison with experimental results obtained from different sources. The Expansion Process in a Counter
