摘要：
This paper presents experimental measurements of flame temperature in the presence of an impact surface and a liquid phase added to the flow. The temperature is measured using laser-induced fluorescence. In the case of a flame of a pre-mixed methane-air mixture with a stoichiometric coefficient Phi = 0.92 and a Reynolds number Re= 1000, a reverse flow zone is detected near the impact surface when this surface is located at a distance of three calibers from the nozzle exit. The temperature field of a gas-droplet flame is measured using laser-induced fluorescence.
