A description of the design of a high speed journal bearing test apparatus and some results recorded from a cylindrical bore bush fed by two axial grooves are presented. These highlight the complex temperature patterns which are generated in the bush. To compliment this detailed information, the variation of load capacity, bush torque reaction, leakage, and bulk outlet temperature with speed are presented also. The work suggests that Taylor’s criterion may be applied broadly to determine the onset of non laminar flow in bearings. It also provides supportive evidence concerning the applicability of design procedures used in the transitional flow regime.
