摘要
Abstract
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.关键词
