Outline of Final Research Achievements |
This study proposes a two-color laser-induced fluorescence technique for measuring the temperature distribution of an airflow by spraying a mist of a fluorescent dye. The mist is generated by using propylene glycol, the vapor pres-sure of which is much lower than that of water, as the solvent of the fluorescent dyes. A supersonic moisture chamber is used as the atomizer for seeding the tracer particles to be visualized. A three-dimensional particle image velocimetry (PIV) method using W-shaped light sheet and color PIV with a digital SLR camera was also developed. The spatial resolution of the z-direction has much room for improvement by increasing the number of cameras. The proposed technique was applied to the measure-ment of the temperature and velocity distribution in a thermal vertical buoyant plume. The proposed technique was found to be very effective for the study of such a thermal structure, and it is well suited for measuring the temperature and velocity field of an airflow.
