The first results of our work concerning the vaporizing methanol droplets temperature measurement on a monodisperse (i.e., monosized and equally spaced) droplets stream are presented. The purpose of this study is the development of an infrared system that is able to measure the temperature of a moving methanol droplet, in order to validate experimentally the models of fuel droplets heating and vaporization. Instead of tracking the droplet along its trajectory, we work with a monodisperse droplets chain and we measure the droplet temperature along the stream. An IR system composed of an extended blackbody, two off-axis parabolical mirrors, and a LWIR monodetector has been built. This paper describes the experimental setup, the measurement principle and presents the first results concerning the temperature measurement along a jet of methanol vaporizing droplets of 200 micrometers in diameter with injection speed up to 5.2 m/s.
