Title:
BOUNDARY LAYER CONTROL DEVICE, BOUNDARY LAYER CONTROL METHOD, WIND TUNNEL TESTING DEVICE, AND METHOD FOR SIMULATING TRAVEL OF VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/023899
Kind Code:
A1
Abstract:
[Problem] To provide a boundary layer control device and a wind tunnel testing device that make it possible to accurately simulate, using a stationary vehicle in a wind tunnel facility, wind velocity distribution and/or flow direction between the bottom surface of a traveling vehicle and a floor surface and/or on the back surface of a rear part of the vehicle. [Solution] A boundary layer control device 10 is characterized by comprising: a boundary layer suction surface 12 that is provided on a floor surface FL so that a vehicle V can be disposed over the boundary layer suction surface 12, the boundary layer suction surface 12 being capable of suctioning a boundary layer of a jet stream MF generated in a space between the bottom surface of the vehicle and the floor surface FL when a jet stream generated in a wind tunnel T is blown onto the vehicle; a suction duct 14 provided under the floor surface FL and opposed to the boundary layer suction surface 12; a suction means 18 for suctioning the boundary layer through the boundary layer suction surface 12; a suction amount adjustment means 20 for adjusting the amount of the boundary layer suctioned by the suction means 18; and a static pressure distribution adjustment means capable of adjusting the static pressure distribution in the front-back direction of the vehicle that is generated in the space between the bottom surface of the vehicle and the floor surface FL when the jet stream MF flows through the space between the bottom surface of the vehicle and the floor surface FL in the front-back direction of the vehicle V.
