Flow simulation of running-in aerostatic spherical bearing with inherent compensation and large wrap angle
A new type of running-in aerostatic spherical bearing with inherent compensation and large wrap angle is designed. For high air supply pressure, large bearing clearance, it was believed that supersonic phenomena are caused and a complex fluid flow is formed in the bearing clearance. However, it is very difficult to obtain the detailed information about the flow phenomenon from flow visualization because of a very thin bearing clearance. Therefore, in order to predict various bearing characteristics accurately for the new kind of bearing, a proper analytical model has to be established and pressure and velocity distribution in the bearing clearance of are obtained by CFD software. It was found that the changes of pressure and velocity just after entering the bearing clearance become very various, but relatively rapid pressure and velocity recovery occurs. In addition, the numerical results presented good agreement with experimental data.
