Static Equilibrium Position, Velocity and Pressure Fields at Static Analysis of Long Noncavitating Elliptical and Offset Journal Bearings

Popis výsledku v původním jazyce

This contribution deals with computational modelling of static analysis of long non-cavitating journal bearings. In this contribution is presented a new theoretical approach to the modelling of a static 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 annd 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 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 solu
