Modeling of Gas Lubricated Compliant Foil Bearings Using Pseudo Spectral Scheme

A methodology for using the pseudo spectral scheme for the modeling of compliant gas lubricated foil bearings is presented in this work. The pseudo spectral scheme is used to obtain numerical solution of the compressible Reynolds’s equation that models the lubricating gas film. This scheme...
