This work presents a computational fluid dynamics (CFD) calculation to investigate the flow field of a vortex cup. The vortex cup utilizes air swirling flow to achieve handling a work piece without any contact. The numerical calculation was performed using the standard
k

ε
model and Reynolds stress model (RSM), and the pressure distribution calculated numerically was compared with the experimental results. It is found that RSM can better reproduce the characteristics of experimental results than the standard

ε
model. Based on the calculation results of RSM, the flow field, spatial pressure and velocity distributions inside the vortex cup were clarified. Furthermore, a visualization experiment was conducted by using ink in water with an enlarged cup, in which the flow was observed and confirmed.
