The main contents and achievements are summarized as follow:1. A theoretical model has been developed to investigate hydrodynamiceffect of mechanical seals with a laser-textured pores seal face.
Finally, numerical simulation based on computer fluid dynamic (CFD) has been made for verifying the effect of hydrodynamic cavitation theoretically.
