Projekční návrhy hydrostatických ložisek obráběcích strojů

Abstract

This thesis is devoted to numerical simulation of flow in journal hydrostatical bearing with method of final volumes in CFD program Fluent 6.3.26. There is chosen a bearing in which is solver corresponding mathematical model numeric by the help of program system Fluent 6.3.26. It was speculate about two dimensional and three dimensional of flow in narrow vacancy of journal hydrostatical bearing. In two dimensional of flow there was defined laminar model for different types of boundary conditions. In three dimensional of flow there were chosen four variants, in two of them there are changes of constructional adjustments of journal hydrostatical bearing. Last variant is modelling of flow in eccentrically shaft support of journal hydrostatical bearing.
