Abstract | Foil bearings are a promising technology that enables high-speed turbomachinery systems. Applications include air cycle machines and turbomachinery for supercritical CO2 cycles. As operating conditions become more challenging, the demand for more comprehensive models to simulate foil thrust bearings has grown. This paper presents a multiphysics multi-timescale computational framework for the three-dimensional and two-way coupled fluid-structurethermal simulation of foil thrust bearings. Individual solvers for the transient fluid flow, structural deformation and heat conduction as well as the coupling strategy are discussed. Next, heat transfer models of the solid structures within foil thrust bearings are also described in detail. The result is a multi-physics computational framework that can predict the steady state and dynamic performance of foil thrust bearings. Numerical simulations of foil thrust bearings with air and CO2 are performed using this framework and new insight into the operation of foil bearings with CO2 is discussed. |
