ABSTRACT:
An array of colorant nozzles, filled with different colors, is placed at an enclosure through which fluid flow is to be analyzed. The array injects the colors into the enclosure with the flow. Color paths through the enclosure are observed and analyzed. The array best spans the enclosure two-dimensionally and injects different colors at different portions of the channel. Controlled timing of injection, e. g. in pulses, and synchronous detection—including tracking leading/trailing ends of color pulses in the enclosure—is best. Specific spatial-temporal color patterns, and 3D observations (as by plural cameras, aimed through windows or a transparent wall, or inside the disclosure) are preferred. For very large systems a careful, exact scale model is used. Preferably a programmed processor operates the array and controls analysis of resulting observed color patterns in the fluid.
