Research on the influence of supersonic phenomena on the gas film flow field of micron-groove-orifice aerostatic journal bearings under high gas supply pressure

To solve the problem of performance degradation caused by supersonic phenomena under high gas supply pressures in orifice-compensated aerostatic journal bearings (OCAJBs), a double-row gas supply micron-groove-orifice aerostatic journal bearing (MGOAJB) is designed, and the SST k-ω turbulence model...

description To solve the problem of performance degradation caused by supersonic phenomena under high gas supply pressures in orifice-compensated aerostatic journal bearings (OCAJBs), a double-row gas supply micron-groove-orifice aerostatic journal bearing (MGOAJB) is designed, and the SST k-ω turbulence model is used to analyze the influences of the supersonic phenomena on the gas film flow field under different gas supply pressures, gas film thicknesses and orifice diameters. Compared with traditional OCAJBs, under high gas supply pressure, supersonic phenomena occur near the gas film inlet in both the MGOAJB and the OCAJB. The Mach number, maximum pressure, temperature and Reynolds number of the OCAJB are higher than those of the MGOAJB, but the MGOAJB has a more stable gas film pressure due to pressure equalization. As the gas film thickness of the MGOAJB increases, the Mach number, Reynolds number and temperature near the gas film inlet increase, but the pressure decreases, the recovery of the pressure and temperature becomes more obvious when the gas velocity drops to a subsonic speed. With increases in the MGOAJB orifice diameter, the pressure, temperature and Reynolds number increase, the Mach number decreases, and the recovery of the pressure and gas temperature becomes more obvious.
