The interaction of fluid film liquid with the rigid body is the main aim of this contribution. The cavitating and non-cavitating long and short journal bearings are taken into account. The Navier Stokes, continuity equations and boundary conditions are the governing equations, which are used for this analysis. Theoretical approach to the analysis of stationary and nonstationary temperature fields is presented. It is presented approach, which allows the separation of liquid and rigid body from each other. Using this approach it is possible to create the database of additional effects from the liquid for given shafts parameter. The Bézier body is used for the analysis. Computational modelling uses the met method. The solution of velocity field is provided in perpendicular co-ordinates and curvy – linear are use by the description of geometrical configuration.
