Abstract

The full field flow tracking technique based on computer-aided image processing in combination with the non-intrusive particle tracking procedure described in Part 1 of this paper is used for quantification of qualitative images of flow in a six-pocket hydrostatic journal bearing. The method uses long distance microscopy (LDM) to evaluate at the same station in time, trajectories, velocities and accelerations throughout the flow field. For accurate and detailed evaluation, a new windowing procedure (WP) and an associated windowing assembly procedure (WAP) are introduced. The combination of WP and WAP brings together the LDM high magnification individually indexed windows into a global picture that yields a more thorough understanding of the total flow pattern.
