The Visualization of an Air Flow in the Clearance of an Externally Pressurized Thrust Gas Bearing by the Heat Curing Oil Film Method : The Rheological Characteristics of Silicone Oil used by Heat Curing Oil Film Method

Abstract

The heat curing oil film method using thermosetting property oil film is a new oil film method. The heat curing oil film method, in which not only the plane flow pattern in wall surface but also oil film thickness of the steady flow can be measured, is newly developed. The rheological characteristics of silicone oil used by heat curing oil film method is investigated for visualization of an air flow in the clearance of an externally pressurized gas-lubricated circular thrust bearing with a central supply hole in this paper.
