METHOD CAPABLE OF INCREASING A DEGREE OF FLOW MEASUREMENT THROUGH A PARTICLE IMAGE VELOCIMETRY BY REDUCING THE REFLECTIVE LIGHT OF A MATERIAL SURFACE, USING A PARTICLE MADE WITH A FLUORESCENT MATERIAL AND THE FLUORESCENT MATERIAL PASSING A FILTER WHICH ONLY TRANSMITTS LIGHT OF A SPECIFIC WAVE EMITTED FROM THE PARTICLE

摘要

PURPOSE: A method capable of increasing a degree of flow measurement through a particle image velocimetry is provided to block the light reflected from a material surface, thereby improve the accuracy of the velocity field information.;CONSTITUTION: A light source(1) emits a monochromatic light which illuminates a fluorescent material. A fluorescent material particle(2) in which the fluorescent material is coated in the particle surface absorbs the monochromatic light emitted from the light source and emits the light of much higher wavelength. A filter(3) transmits only the light of a high wavelength which is emitted from the fluorescent material particle.;COPYRIGHT KIPO 2013;[Reference numerals] (3) Blocking light whose wavelength is λ; (6,8) Wavelength : λ; (7) Wavelength : λ + α
