Abstract
The vortex cup is proposed as a method to transport sensitive products such as silicon wafers in manufacturing. Air through the inlet nozzle located at the top of the vortex cup flows to form a swirl in the cylinder. The flow located in the lower part of the thin gap between the vortex cup and the bottom surface escapes and generates a negative pressure that can lift objects. In this research, three-dimensional numerical simulation of the air flow field in a vortex cup is performed, and a comparison of the simulation and experimental results shows very good agreement. In addition, the vortex cup length and shape that affect the negative pressure were applied to the analysis. Through the simulation results, optimum conditions for the vortex cup shape were proposed.
