ABSTRACT:
Gas journal bearing systems are provided. An exemplary gas journal bearing system comprises a vortex generator, a housing and a journal. The vortex generator is operative to receive a flow of gas and to impart an angular acceleration to the gas. The housing is in fluid communication with the vortex generator, with housing having a first exhaust through which the gas is exhausted. The journal is supported within the housing by a vortex of the gas as the gas swirls along at least a portion of a length of the journal. Methods and other systems also are provided.
