To study the lubrication performance of tilting-pad thrust bearing (TPTBs) during start-up in nuclear pump. a hydrodynamic lubrication model of TPTBs was established based on the computational fluid dynamics (CFD) method and the fluid-structure interaction (FSI) technique. Further. a mesh motion algorithm for the transient calculation of thrust bearings was developed based on the user... https://rbdoutlet.shop/product-category/mens-shirts/
