Experimental results are presented, relating to friction factors and circumferential pressure distributions, for a plain cylindrical ,journal bearing with a central circumferential inlet groove. The length-diameter ratio of each journal bearing land was 0.25 and the clearance ratio was 0.0031. The friction factor results showed the existence of a distinct 'transition regime', characterized by a pronounced 'hump' in the friction factor-Reynolds number relationship. Pressure measurements recorded when operating in this transition regime revealed the inadequacy of many existing 'turbulent' theories for superlaminar lubrication. By using a short-bearing theory a good correlation of the pressure distribution results was obtained, in terms of a non-dimensional viscosity parameter, k,, which is dependent on both the eccentricity ratio and Reynolds number. The magnitude of k, in this regime was considerably higher than the corresponding value for laminarflow, and was similar to the magnitude predicted.from a simple theory based on relating k , to the variation of measured friction factor with Reynolds number.

An extensive survey of the experimental research on the static and/or dynamic characteristics of fixed geometry, hydrodynamic journal bearings, available in English, in the open literature is presented. The type(s) of bearing, size of bearing(s) and range of parameters measured in each work are reported for slightly over 100 published experimental works. In addition, some general observations about the available experimental data sets are made. This annotated survey is intended to help the analytical community by providing an extensive list of sources of experimental data for use in analysis verification. It is intended to help the experimental community by highlighting the shortcomings of the available literature, as well as by providing a list of sources for appropriate data to help with current and future test rig debugging.
