Abstract: Gasexpanded lubricants (GELs) are tunable mixtures of synthetic oil and carbon dioxide that enable dynamic control of lubricant viscosity during bearing operation. This control can help reduce bearing power loss and operating ...

Abstract: Gasexpanded lubricants (GELs) have the potential to increase bearing energy efficiency, longterm reliability, and provide for a degree of control over the rotordynamics of highspeed rotating machines. Previous work has ...
