|発明の名称||NON-CONTACT GAS TEMPERATURE MEASUREMENT METHOD AND DEVICE|
PROBLEM TO BE SOLVED: To provide a non-contact gas temperature measurement method and device capable of measuring a temperature distribution of gas with high precision, thereby solving a problem that a technique for enabling non-contact multi-point temperature measurement according to a NO-LIF method causes a temperature value of gas to vary about several tens K due to reactivity of NO, whereas a method of using a fluorescent dye in water makes it difficult to apply the fluorescent dye as it is because of difference of stability and diffusibility of the fluorescent dye within the gas.
SOLUTION: A gas targeted to be a temperature measurement is sprayed with a fluorescent dye solution so as to be made into a droplet group, and light having a wave of the excitation wavelength region of the fluorescent dye is irradiated on this droplet group, thereby measuring a fluorescence intensity of the fluorescent dye and calculating a temperature from this fluorescence intensity.
