Structural Optimization of Non-Contact Vortex Negative Pressure Carrier
Simulation models based on the different structural levitation vortexes were built, the analysis on the flow characteristics of pressure distribution and bearing capacity was conducted by using the RNG κ-ε turbulent model and non-uniform meshing in variable working conditions. At last, the influence factors and variation rules of vortex adsorption negative pressure effect were obtained. The theory and the experiment results indicate that the vortex carrier with symmetrical tangential air supply has the optimal stability, but the optimal negative pressure effect and the great lifting force are obtained by the vortex carrier with tangential single air supply.
