Effects of geometric parameters on the separated air flow temperature of a vortex tube for design optimization

Improving vortex tube performance based on vortex generator design

“…These three parameters have influence on interchange of mass and energy inside of vortex tube. The effects of inlet nozzle area and cold orifice diameter have been previously studied by many researches such as Singh et al [17], Im and Yu [18] and Nimbalkar and Muller [19] for air as the working fluid. But the influence of these parameters on variation of optimum cold mass fraction has not been studied.…”

Experimental study of the energy separation in a vortex tube

“…In terms of the effect of the cold mass flow ratio on the vortex tube, in Markal's et al (2010) experiments, the maximum points of ∆T c and ∆T h appeared nearly at µ c = 0.25∼0.4 and µ c = 0.85∼0.9, respectively. Also, Im and Yu (2012) found the minimum value of ∆T c was observed at µ c =0.6 while the maximum value of ∆T h was observed at µ h =0.9. Though abundant data of the influence of different parameters on the vortex tube exits, the mechanism of the influence still requires investigation.…”

Parametric Review of Ranque-Hilsch Vortex Tube

“…Figure 10 shows the various valve angles researchers used during analysis. Many researchers during their experimental studies (Marshall, 1977;Dyskin, 1989;Aydin & Baki, 2006;Dincer, Baskaya, Uysal, & Ucgul, 2009;Markal, Aydin, & Avci, 2010;Dincer, Yilmaz, Berber, & Baskaya, 2011;Devade & Pise, 2012;Im & Yu, 2012;Avci, 2013;Devade & Pise, 2014) have used different valves Bovand, Rashidi, & Esfahani, 2016) and shapes. Dyskin (Dyskin, 1989) used detwister on hot end and observed that the heating effect increase by 3 to5 0 .…”
