| dc.description.abstract | This article reports the effect of double vortex-chambers with multiple inlet snail entries of N = 1, 4 and 6 nozzles on the energy separation referred to cold gas exit temperature difference (ΔT<inf>c</inf>) in a counter-flow vortex tube type. The experimental work focused on ascertaining the effects of entry air pressure (P<inf>i</inf> = 2, 3 and 4 bar), distance ratios between the two vortex-chamber to the vortex tube diameter (l/D = 0.875–1.125) and the cold gas mass ratio (μ<inf>c</inf>) in a vortex tube. It was found that cold gas exit temperature difference (ΔT<inf>c</inf>) increased with increasing inlet air pressure (P<inf>i</inf>) and number of inlet nozzles (N), and decreasing l/D. Among the studied conditions, the double vortex-chamber operated at the highest P<inf>i</inf> of 4 bar, N = 6, the smallest l/D = 0.875 and μ<inf>c</inf> = 0.38 gave the highest cold gas exit temperature difference (ΔT<inf>c</inf>) of 31.5 °C. In addition, the deep learning optimization technique was also developed to predict the temperatures for different combination of parameters used in this study. It was found that the optimal models provide maximum R<sup>2</sup> value of 0.99317. | |
