Abstract: Air foil bearings are used in turbomachinery applications with high speeds and in oil-free environments. Their numerical analysis has to account for the multiphysicality of the problem. This work features a detailed ...

Abstract: A detailed analysis of the effective thermal resistance for the bump foil of air foil bearings (AFBs) is performed. The presented model puts emphasis on the thermal contact resistances between the bump foil and the top ...

Abstract: A detailed elastogasdynamic model of a preloaded three-pad air foil journal bearing is presented. Bump and top foil deflections are herein calculated with a nonlinear beamshell theory according to Reissner. The two-dimensional ...
