基于N2 S方程、J2E湍流模型和周期性边界，在额定转速下对不同油膜厚度和瓦面倾角下的推力油槽进行了CFD数值模拟。利用Autocad和Proe建立了1/12推力油箱模型，并作适当简化，采用分块网格技术对计算区域进行了网格划分；然后在Fluent 中采用SIMPLEC算法进行了计算；最后通过后处理得到了瓦面各部分的压力分布、不同膜厚和倾角与瓦面承载力的关系曲线以及油膜不同厚度层下的速度分布，这对推力轴承的设计、检修、运行有着重要的指导意义。

Based on the N2S equation, J2E turbulent model, and periodic boundary, CFD numerical calculation and analysis w as performed on the tank of thrust bearing under the rated speed with different oil film thicknesses and tile surface angles. The 1/12modelofthethrusttankwasestablishedusingthetoolofAutocadandProeandthecomputationaldomainwasdiscretized using the clumpy gridding technology. SIMPLEC algorithm in Fluent was used to perform the simulation. The calculation re2 sults w ere post2processed to determine the pressure distribution of tile surface, the relation curves between oil film thickness, tile surface angle, and bearing capacity of tile surface, and the velocity distribution with different thicknesses of oil film,which can better guide the design, maintenance, and operation of thrust bearing.
