Various papers were dedicated to the technical and industrial aspects of the Taylor–Couette flow, by analyzing the flow structure in dependence of characteristic parameters. Also some studies concerning the influence of an eccentrical position of the rotating inner cylinder relatively to the fixed outer cylinder exist in the case of a large gap width. The principal technical application of such studies is the flow in journal bearings where the gap width is very small, of the order 0.1\% relative to the inner cylinder radius. Analytical and numerical investigations of the flow in journal bearings are generally based on the two–dimensional Reynolds approximation. This investigation in aiming at a validation of the range where the Reynolds equation is applicable in relation to the characteristical parameters: gap width, eccentricity and Reynolds number.
