摘要：
A theoretical model is developed to study the effect of partial laser surface texturing (LST) on a hydrostatic gas seal. The partial LST provides a mechanism for hydrostatic pressure build up in the sealing dam similar to that of a radial step. The surface texturing parameters are numerically optimized to obtain maximum efficiency in terms of the ratio of load carrying capacity over gas leakage. The performance of the optimum partial LST seal compares favorably with that of a radial step seal.
