Title:
Prediction of stiffness coefficients for foil air bearings to perform rotordynamic analysis of turbomachinery 
Pages contribution:

Abstract:
This paper studies foil gas bearings for the small-size high-speed turbomachinery applications. The main part of the work is devoted to the modeling of the foil gas bearings using computational fluid dynamics (CFD). Deformation of compliant elements is incorporated directly into the CFD model by means of analytical expressions and moving mesh technique. The CFD model is used to predict load capacity and rotordynamic stiffness coefficients of the foil bearing. The studied bearing is a multi-leaf fo...    »
