摘要： A device for measuring a wall surface cooling characteristic of a gas turbine combustor and a modeling method thereof are provided. The device includes a hot flow inlet section, a cold flow inlet section, and a gas discharge section, where the cold flow inlet section is communicated with an experimental section; the cooling structure model is a flat plate structure; a tail end of the experimental section is provided with a thermocouple threading seat; the gas discharge section is provided with a laser injection window; and the experimental section is provided with an infrared thermal imaging measurement window and a visual observation window. The modeling method includes: modeling the wall surface of the gas turbine combustor into the flat plate structure; determining a pressure, a temperature, and a velocity on a hot flow side of the device; and determining a material and a thickness of the cooling structure model.
