Performance of an externally pressurized rectangular gas bearing under constant effective recess pressure

The present study predicts the performance of an externally pressurized rectangular recessed gas bearing under different operating conditions. The analysis makes use of simplifying assumptions and an empirical formula which relates the recess pressure to the bearing supply pressure. A comparison between the theoretical results obtained and available experimental data shows qualitative agreement. There are some deviations in pressure distribution and load-carrying capacity especially at greater film thickness and supply pressures. The reasons for these deviations are discussed.
