Abstract:

In order to reveal the effect of flow characteristics on the load capacity of oil cavity, the flow of round Rayleigh step cavity in hydrostatic lift was divided into three regions: the axisymmetric jet impinging flow, radial source flow and film flow. The computational fluid dynamics (CFD) method was used to build a calculation model and the influences of geometry (e, h) parameters and the Reynolds number on the vortices were simulated. The results show that there are complex vortices in the flow field of the round Rayleigh step cavity, of which the pressure is higher than parallel disks flow. The number of vortices is different from 1 to 4 with the Reynolds number of 200
