摘要：
A new type of hydrodynamic laser surface texturing gas seal with orientation ellipse dimples is introduced to improve hydrodynamic effect. Theoretical model is developed to study the hydrodynamic effect of this new gas seal. Then, a parametric investigation of the texturing parameters such as slender ratio, dimple inclination angle, dimple depth, and dimple area rate is presented for the presented gas seal under different operating parameters of rotation speed, seal pressure, and clearance. Results show that the orientation dimples can greatly improve hydrodynamic effect of laser surface texturing gas seals. Open force may be improved more than 20% greater by hydrodynamic effect in the analysis.
