“…(10) can be solved in a loosely coupled manner, either using the linearized form and the full non-linear form of the equations. Numerical methods employing finite volume and finite difference schemes to discretize the source and partial derivative terms are routinely used [4,18,7,19].…”

“…Hence to compare the pressure generating ability, the eccentricity ratio of the foil bearing is increased such that the minimum film thickness is maintained same as that of rigid bearing, as in Ref [4]. The mid plane pressure distribution for both rigid and foil bearing cases are compared with numerical results of Peng [4] which is widely used as a validation case [19,24]. This solution was obtained with a finite difference scheme and was validated with the experimentally obtained load carrying capacity.…”

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 is coupled to a structural model that models the compliant structure of the foil bearing. The coupled simulation model is applied to both one dimensional and two dimensional cases. The simulation model is validated by comparing its results with analytical solution for short bearing case and to published data for compressible two dimensional cases. The advantages of using this scheme compared to a finite volume scheme for the simulation of foil bearings are presented.
