For a specific aerostatic journal bearing, the given parameters are: the diameter of bearing D=100 mm, the length of bearing L=100 mm, the angular velocity of bearing ω=0, the row number of orifice n=2, and the column number of orifices m=8; the parameters of mesh gird size M=64 and N=20; and the convergence condition E0=10−6 and a recommended convergence rate factor δ=0.05. Fig. 12(a) and (b) show that the pressure distribution for the eccentricity ratios of ε=0.05 and ε=0.25 respectively under the supply pressure p0=0.5 MPa.
