New configurations for sea water desalination system using Ranque-Hilsch vortex tubes

Application of new series connection scheme of vortex tubes in seawater desalination unit using new vortex generators

“…Several experiments were carried out, to investigate the proposed RHVT/seawater desalination performance, with a new series arrangement under different vortex generator new materials of PC and PA6. Subsequently, elaborated analysis of the system temperature behavior, desalination rate and freshwater production were compared with previous work of Shmroukh et al [13].…”

“…Moreover, the system high performance was given by using methane rather than air. On the other and, Shmroukh et al [13] developed new RHVTs simple arrangements to increase the system desalination efficiency and overall performance. Their results demonstrated that using simple series hot vortex tubes arrangement (SHVT) increased the desalinated water production to reach up to 79% of the initial quantity.…”

“…The setup is consisted of two identical RHVTs arranged in series with new configuration, the used RHVTs had two identical vortex generators with 25 mm in diameter, 35 mm in length and 1.3 mm nozzle groove depth, while, the hot tube had a length (L) of 150 mm and a diameter (D) of 7.5 mm, moreover, the vortex chamber inner and outer diameters were 25 and 35 mm, respectively, with a length of 50 mm, moreover, the inner diameter of the air inlet tube was 7.5 mm and the diameter of the cold orifice was 8 mm. While the vortex generator had 3 nozzles (N) as maintained by [13]. A compressor was maintained at 4 bar to generate the main Fig.…”

“…Furthermore, Fig. 8 illustrated the behavior of the main cold air temperature for both modified arrangements, compared with that for the simple SHVT arrangement of Shmroukh et al [13], with respect to total experimental time. It was obviously seen from the figure, that the temperature of cold airstream in the main cold line of the condenser was decreased with time except for SHVT of [13], till it reached its minimum value after 180 min.…”
