Abstract
The method is used for uniforming temperature in a shaft supported by a fluid bearing during rotation of the shaft; a journal portion of the shaft is located inside the fluid bearing; at least one passage is provided inside the shaft at least along the journal portion so to cross it; at least one flow of heat-exchange fluid is established in the at least one passage; the method allows to overcome the problems due to the 'Morton effect'. A bearing system implementing the method is advantageously used in a turbomachine.
