Abstract
An externally pressurized porous gas bearing for operating within a refrigerant environment is disclosed. The gas bearing utilizes shear heating from rotation of a rotor, thereby increasing the pressure and load capacity of the externally pressurized porous gas bearing. The gas bearing is capable of operating when the refrigerant is in a liquid phase and when the refrigerant is in a gaseous phase.
