A direct method of computation that fully allows for hydrodynamic effects has been devised for the correct design of externally pressurized journal bearings fed with in compressible lubricant. With this method, the performance of bearings with independent and with crossrelated recesses were analyzed thoroughly, and the influence of hydrodynamic effects and the feeding system on bearing stiffness was determined.
