볼텍스 컵의 최적화를 위한 전산유동해석 = Computational flow analysis for the optimization of the vortex cup

다국어 초록 (Multilingual Abstract)

The vortex cup is an effective method of non contact handling by creating suction pressure using tangential velocity. Air supplied from tangential nozzle inlet is rotated inside vortex cup and drained through the gap between the object and the vortex cup. This swirling air flow create suction pressure and at the same time have the lifting force to raise the object. In this paper, three dimensional numerical simulation of the air flow field in vortex cup are performed. The characteristics of the vortex cup and according to the conditions the suction pressure generated by the flow rate, the length of the vortex cup, the gap between the cup and the bottom surface and the throat diameter of the vortex cup are analyzed. Finally, through numerical results optimal conditions of generating suction pressure are presented to pickup the objects.
