Résumé

Although the vortex tube had been invented over 80 years ago, its design method on the key structure parameters has not be achieved because of the complex swirl flow and its special energy separation phenomenon. In this paper, a new design method is proposed, based on the flow structure and the unsteady oscillation of the fluid flow. The energy separation phenomenon is modeled with the unsteady processing vortex core, which combined the flow field, the heat and mass transfer process in the vortex tube. And then, the optimization criteria for the main tube design can be achieved. The PIV/LDV is adopted to derived the steady and unsteady fluid field characteristics, to present the verification. Not only does the experimental performance of vortex tube based upon this method show exciting improvement, but also present better feasible and wider future for the vortex tube.
