English abstract

This contribution deals with computational modelling of a static analysis of the long and short journal bearings. In this contribution is presented a new theoretical approach to the modelling of the static and dynamic behaviour of the rigid rotating body in real liquid. The approach is based on the application of Navier-Stokes motion eq., equation of continuity and boundary conditions eqs. It is possible to separate the motion of the rigid body and real liquid from each other using suitable transformation relations and then it is also possible to separate the stationary and nonstationary motions from each other. A method of control volumes is used for these analyses. The real Bézier body is used for description of the geometrical configuration and also for the approximation of velocity and pressure functions. The combined ALE (Arbitrary Lagrange-Euler) method is used, because it´s necessary to generate a new net (perform new meshing) for a change of the shaft position. Some results of the numerical solution of the model task are presented in this contribution.
