PROBLEM TO BE SOLVED: To provide a wind tunnel experiment device having high versatility, and increasing efficiency in an experiment and the like. SOLUTION: The wind tunnel experiment device includes: a straightening part 11 for forming the whole air current flowing in an air duct R as a uniform and nonturbulent air current; a turbulent flow control part 12 for imparting an average speed and the turbulence distribution required for the experiment to the uniform and nonturbulent air current; a turbulent flow diffusing part 13 for further diffusing turbulence caused in the turbulent flow control part; and a smoke source part 14 arranged while being protruded in the air current from a body part of a wind tunnel forming the air duct and discharging smoke from a smoke discharge port 14a arranged on the tip, toward the downstream side from the upstream side in the wind axis direction of the air duct. The device is characterized in that a distance between the downstream end of the straightening part and the upstream end of the turbulent flow control part is 3-5 m, and a distance between the upstream end of the turbulent flow diffusing part and the upstream end of the smoke source part is 4.5-5.7 m, and a distance between the downstream end of the straightening part and the upstream end of the smoke source part is 15.7-17.7 m.
