Abstract : The hydrodynamic theory of foil bearings is reviewed. The relationship between fluid pressure and film thickness is discussed. The compressibility of gas is included in the analysis. It is shown that the basic equation for determination of pressure distribution becomes a third order boundary value problem in terms of film thickness. A simple numerical scheme for solution of the nonlinear boundary value problem is developed and some examples are considered and discussed. (Author)
