Application and comparison of different turbulence models in the three-dimensional numerical simulation of non-contact swirl sucker

In this paper, k-ε model, RNG k-ε model and k-ω model were used for non-contact swirl sucker to the three-dimensional numerical simulation. Block division technology was used for meshing non-contact swirl sucker, the part of vortex cup was meshed by unstructured grids and the part of gas film was meshed by structured girds. The pressure distribution, the lifting force and the flow rate characteristics were conducted by the three different turbulent model. Compared the simulation results and experiment results, it was known that RNG k-ε model could reproduce the real distribution. This model can be used to understand the influence of handling variables such as the standoff distance and air flow rate on the pressure distribution and lifting force acting on the handled object.
