摘要: The paper concerns the hydrodynamic turbulent motion in lubricant layer. Proceeding from Reynolds equations and introducing approximations currently used lubrication problems, owing to film thickness, general for are written.Using Prandtl mixing length hypothesis, exact approximate solutions obtained velocity distribution into results discussed by pointing out pressure gradient number influence on distributions, as well differences with respect laminar flow.In order obtain simple formulae, dependence of rate flow a dimensionless form is replaced linear relation, slope which depends number. This approximation allows obtainment differential equation under form. integrated case journal bearings, assuming...
