System and method to measure 3D flow characteristics of a gas

摘要

A method to collect 3D measurement data regarding a working fluid in a system, e.g., a turbo-machine, including: arranging sources of beams proximate to a passage of the working fluid in or downstream of the turbo-machine such that beams from the sources are projected through the working fluid; detecting intensities of the beams after they pass through the working fluid, and generating at least a two dimensional (2D) representation of the working fluid based on the detected intensities of the beams.

1. A method to collect data regarding a working fluid in a system comprising:
arranging sources of beams proximate to a passage of the working fluid in or downstream of the system such that beams from the sources are projected through the working fluid, wherein the beams are arranged in planes traversing the working fluid, the planes are separated along an axis of the system, and the beams intersect at points within each of the planes; detecting intensities of the beams after they pass through the working fluid, using the detected intensities, determining data values representing a condition of the working fluid at positions in the planes corresponding to the intersections of the beams; comparing the data values associated with one of the planes to data values associated with another of the planes, and generating at least a two dimensional (2D) representation of the working fluid based on the comparison of the data values, wherein the at least 2D representation indicates changes in the working fluid as the working fluid flows between the planes.
