Abstract: Standard k-ε turbulent model, RNG k-ε turbulent model and RSM turbulent model were used to simulate for non-contact vortex gripper. Through the simulation calculation, the pressure distribution, lifting force and flow rate characteristics of the three turbulent models were obtained respectively. Comparing the three turbulent models’ result with experimental result, RSM turbulent model is the most reasonable. RNG k-ε turbulence model forecast results take second place and in the engineering application the error of this model is acceptable. Standard k-ε turbulence model forecast result is the worst. RSM turbulent model and RNG k-ε turbulent model could be used as theoretical basis of the product upgrades.  

Key words: non-contact vortex gripper, turbulent model, numerical simulation
