Numerical Simulation of Computational Fluid Dynamics (CFD) of the Micro-Scale Flow Field in the Spiral Groove Dry Gas Seals

A spiral groove three-dimension model was founded using Solidworks software,the model was latticed using the pre-treatment Gambit of Fluent software,a numerical simulation was made for the internal micro-scale three-dimension flow field under a special condition of the spiral groove dry gas seals using Fluent software,the distributions of the pressure and velocity of the flow field,and leakage were obtained,the flow data derived agreed well with the experimental data in literatures.The distributions of the pressure and velocity of the flow field,and leakage under different parameters were obtained through the second numerical simulation after the operation parameters were changed,and the influence of the operation parameters on the spiral groove dry gas seals was analyzed.
