Effects of operating conditions and supply hole diameter on the performance of a rectangular aerostatic bearing

Performance characteristics of an elliptic hydrostatic bearing and comparative analysis based on Stokes’ conditions

“…Also it increases by increasing the supply hole diameter to pad outer length ratio. Otherwise, the total thrust decreases by increasing the film thickness and/or decreasing supply pressure [33].…”

Identification of Discharge Coefficients of Orifice-Type Restrictors for Aerostatic Bearings and Application Examples

“…With both methods, however, the validity of the result is limited to a narrow parametric range. Alternatively, the discharge coefficient can be evaluated experimentally through flow rate and pressure measurements on the actual system Kassab et al, 1997, for example, present an experimental investigation of the effects of varying supply hole dimensions and supply pressure on the performance of aerostatic bearings, where the consumption and pressure distributions thus obtained can be used to study discharge coefficients. On the basis of this idea, Belforte et al, 2007, present an experimental study of annular orifice and simple orifice air bearing feeding systems which was carried out in order to identify the discharge coefficient as a function of the above parameters using analytical formulations.…”

CFD Investigation of an Aerostatic Thrust Bearing Flow Field with New Type of Throttling Structure

“…Many investigators [5][6][7][8][9][10][11] have focused both theoretically and experimentally on studying the static and dynamic performance in air thrust bearing. Many studies have revealed the existence of an undesirable pressure depression for bearings operating under large bearing clearances, high air supply pressures, or high mass flow rates, in these works, a circular aerostatic thrust bearing with a single hole is always used.…”
