A new aerostatic thrust bearing was investatged using Computational fluid dynamic (CFD) method in this paper. The throttling structure of the aerostatic thrust bearing in this paper is an annular gap type. The CFD software FLUENT was used for solveing NS equations. SST k-ω was used to serve as a turbulent flow model for the two dimensional axis fluid field. The load capacity, air flow rate at different bearing clearance and supply pressure were obtained by numerical simulation. The flow details such as pressure and mach number at different bearing clearance were disccused. The results shows that, there is stable a high pressure zone of new aero thrust bearing. If the supply pressure or bearing clearance is high enough, the supursonic flow will occur in the throttle annular gap, and an oblique shock wave is produced around the end of gap.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
