摘要： PROBLEM TO BE SOLVED: To provide a method and a system for gas flow visualization which can visualize a gas flow passing through a flow channel with a very small diameter or gap, especially a gas flow such as air in a fuel cell, easily and sufficiently.
SOLUTION: The gas flow visualization system comprises a fluorescent mist/air flow generation device 3 which generates fine fluorescent oil mist from fluorescent oil 33 prepared by solving a fluorescent agent in oil and supplies it to the air to generate a fine fluorescent oil mist/air flow 34; a light irradiation device 4 which irradiates the fine fluorescent oil mist/air flow 34 with light L1, generates fluorescence from fluorescent oil mist constituting the oil mist/air flow 34, and visualizes an air flow 12 in a flow channel 12a; fluorescent detection means 65 to 67 for detecting fluorescence; and a display 67a for visually displaying the air flow in the flow channel 12a on the basis of the detected fluorescence. As compared to a method using powdery particles in a conventional technique, the air flow is visualized without changing the shape of a flow channel and without staining a visualization section.

摘要： PROBLEM TO BE SOLVED: To provide a measuring means for velocity distribution in micropassages having spatial resolution in the order of micrometer, and capable of acquiring three-dimension (x, y, z) and three-component (u, v, w) information.
SOLUTION: The measuring means has an optical irradiation means for irradiating, with light, a flow field in a micropassage supplied with minute tracer particles, an image pickup means for picking up an image of the flow field, a focal plane set means for changing its focal plane to an arbitrary position, and an analysis means for finding velocity distribution in the micropassage. The image pickup means picks up at least three images at very short intervals of time continuously, at positions of at least two kinds of focal planes set by the focal plane set means, and the analysis means analyzes the obtained images, and finds the velocity distribution of the three components in the directions of the x-axis, y-axis, and z-axis.
