... machine bearings turbomachinery gas foil bearing thermohydrodynamics Lobatto point quadrature Lobbato point quadrature algorithm, which is utilized in this paper, was first proposed to solve the lubrication problem by Elrod and Brewe ( 10 ) and Elrod ( 11 ). In the following years...

...Sébastien Le Lez; Mihai Arghir; Jean Frene The performance of gas foil bearings (GFBs) relies on a coupling between a thin gas film and an elastic structure with dissipative characteristics. Because of the mechanical complexity of the structure, the evaluation of its stiffness and damping is still...

...Tae Ho Kim; Luis San Andrés Commercial oil-free microturbomachinery implements gas foil bearings (GFBs) for reliable performance with improved efficiency. However, GFB modeling is still largely empirical, lacking experimental validation. An analysis of simple GFBs operating at large shaft speeds...
