Investigation of Real Time Issue in Visualization of Velocity Field in Oil Film

In order to create a virtual flow analysis system for thrust bearings, a new method of particle texture mapping (PTM) for flow field visualization was presented. By utilizing the common graphical accelerator, PTM has achieved high speed, good image contrast, easy to control its particle decay process and matching the experimental results fairly well. The study is helpful to reveal the mechanism of evolution and thermo-exchange of oil films.
