The gas foil bearing (GFB) technology is a key factor for the transition to oil-free rotating
machinery. Among numerous advantages GFBs offer the unique ability to be lubricated with
working fluids such as refrigerants. However the computational analysis of
refrigerant-lubricated GFB-rotor systems represents an interdisciplinary problem of enormous
complexity. This work pushes forward existing limits of feasibility and establishes a new
strategy that enables stability and bifurcation analyses.
