PROBLEM TO BE SOLVED: To provide a wind tunnel device capable of more precisely performing wind tunnel test.;SOLUTION: A wind tunnel device includes: a measurement chamber 3; a jet nozzle 5 for blowing air flow W (main jet V) to the measurement chamber 3 via an opening; and a pressure wave generation unit 10 for delivering a pressure wave having a fluctuation distribution in a circumferential direction of the opening from an outer peripheral side of the opening of the jet nozzle 5 toward a circulation direction of the air flow W (main jet V) in the measurement chamber 3. Thus, generation of vortex flow can be suppressed or delayed to allow more precise wind tunnel test to be performed.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
