1008 Visualization and Measurement of Pressure Distribution in Externally Pressurized Gas Thrust Bearings by using Pressure-Sensitive Paint

Abstract

This paper describes visualization and measurements of pressure distribution by using Pressure-Sensitive Paint (PSP) for externally pressurized thrust gas bearing. The test bearing diameter is 30 mm. Numerical calculation of pressure distribution was carried out using divergence formulation method. Obtained results by experiments were compared with calculated results, it was quantitatively evaluated.
