Abstract	For better geometric parameters of Spiral Grooved Dry Gas Seals, the numerical simulation is carried out, based on the Navier-Stokes (N-S) equation, the laminar model and the SIMPLEC algorithm. Five geometric parameters are investigated emphatically, use one by one optimize method, take opening force, leakage, gas film stiffness and the ratio of stiffness and leakage as the assessing target. Finally, the optimized parameters are gained, and a comparison between original and optimized parameters is put forward. The result shows, when h less than 4μm, the value of K and K/Q have a considerable relative increment, especially when h less than 2μm, the increment preponderate over 13% and increasing vividly, this will improve seal performance evidently, higher stable is gain.
