Limits of applicability of the Stokes model in the calculations of sliding bearings

Akhmetov V. K.

Viscous incompressible fluid flow in sliding bearings is calculated numerically. The main attention is paid to the study of flow separation regimes in the axial region of the flow with the formation of recirculation zones. The critical values of the parameters for the occurrence of separation are determined. The calculations are compared with the available data in which the Stokes model was used.
