This work is concerned with the development of a numerical bearing model with which the flow in a hydrodynamically lubricated journal bearing can be computed in three dimensions. It was produced in the course of the industrial research project “CFD-Gleitlager”, which was funded by the Industrielle Gemeinschaftsforschung und -entwicklung (IGF) within the Arbeitsgemeinschaft industrieller Forschung (AiF) and ultimately supervised by the Forschungsvereinigung Verbrennungskraftmaschinen (FVV).

The solver for three-dimensional flow problems in bearing geometries presented here is a basic flow solver, which is to be extended by cavitation modelling in the later course of the project. This means that an incompressible flow with constant temperature and viscosity is initially assumed, in order to carry out the three-dimensional computation of the flows in a wide variety of cylindrical gap geometries as efficiently as possible. The displacement of the rotating shaft is taken into account in this work. The open source toolbox OpenFOAM ® serves as the basis.
