Abstract
In this study, we investigated the tip structure of a swirling cup numerically to obtain a stable non-contact gripping force by changing the tip length, tip groove, and guide block. Swirl number is considered for each position inside the cup according to the non-contact gap and flow rate. The results show that the effective gripping force occurs at the gap size of 0.6-0.8 mm. If the tip length increases, the upper boundary of the effective non-contact gap extends to 0.9 mm without losing gripping force. Contrariwise, when the total cross-sectional area of the groove is 13% of the area of the entire discharge gap, the lower boundary of the effective non-contact gap extends to 0.3 mm and accompanies an improved gripping force.
Additionally, the inverted T-shaped guide block inside the cup stabilizes the cyclone flow pattern of the swirling cup.
