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

Abstract In this work, an experimental study on new series connection of two Ranque-Hilsch vortex tubes with generator materials, potential in seawater desalination was implemented, combined modification has not been studied open literature. Polycarbonate and Polyamide-Nylon 6 were tested compared as materials that enhance the heat transfer between air streams inside tube. Moreover, using preheater by utilizing waste exit stream from last tube arrangement. The results revealed hot fraction both arrangements should be kept at 0.5 for optimum performance. modified arrangement had higher evaporator main temperature lower condenser cold than generator. Furthermore, desalinated water percentage reached about 94% 89%, respectively. Therefore, based is recommended use applications.
