摘要： An airflow adjusting apparatus to be provided in a vehicle includes a first airflow generator and a second airflow generator. The vehicle includes a front wheel and a rear wheel that are disposed in a vehicle longitudinal direction to be partly protruded from a bottom surface of a vehicle body of the vehicle downward in a vertical direction of the vehicle body. The first airflow generator is provided on the bottom surface of the vehicle body and behind the front wheel, and configured to generate a first airflow moving backward of the vehicle. The second airflow generator is provided on the bottom surface of the vehicle body and behind the first airflow generator, and configured to generate a second airflow that deflects, vehicle-widthwise inward, an airflow flowing in from a side on which the first airflow generator is disposed.

摘要： An airflow adjusting apparatus to be provided in a vehicle includes a flap and an airflow generator. The vehicle includes a wheel disposed to be partly protruded downward from a vehicle body of the vehicle. The flap is protruded, in front of the wheel, downward from the vehicle body. The airflow generator is provided in an underneath of the vehicle body and vehicle-widthwise inwardly from the wheel. The airflow generator is configured to generate an airflow vehicle-widthwise inward, and backward of the vehicle. The airflow moves obliquely relative to a vehicle longitudinal direction when the vehicle travels forward.

摘要： An airflow adjusting apparatus to be provided in a vehicle includes a road clearance detector, an airflow generator, and a processor. The vehicle includes a vehicle body, a wheel attached to the vehicle body to be partly protruded downward from the vehicle body, and a suspension that holds the wheel to permit the wheel to make a vertical stroke relative to the vehicle body. The road clearance detector is configured to detect a road clearance. The road clearance is a vertical distance from a road surface to an underside of the vehicle body. The airflow generator is provided in an underneath of the vehicle body, and configured to generate an airflow. The processor is configured to allow the airflow generator to generate a downward airflow having a downward speed component, on the condition that the road clearance has been on the increase.

摘要： An airflow adjusting apparatus includes a duct, a duct opening-closing unit for the duct, first and second airflow generators, and an airflow adjustment processor. The duct has an inlet open toward a front of a movable body and an outlet that guides an airflow to an air-blowing target inside the movable body. The first and second airflow generators are provided respectively on first and second faces, opposed to each other, of an inner surface of the duct. The airflow adjustment processor performs, if the duct opening-closing unit is closed, vortex flow formation control of causing the first airflow generator to generate a first airflow that directs to the outlet side with respect to the duct and causing the second airflow generator to generate a second airflow that directs to the inlet side with respect to the duct.

摘要： An airflow adjusting apparatus to be installed in a vehicle includes two or more outward airflow generators and a controller. The outward airflow generators are disposed side by side in a vehicle front-rear direction in vicinity of an outer edge in a vehicle widthwise direction on an upper surface of a vehicle body on a front side of a windshield. The outward airflow generators are each configured to form an outward airflow with respect to the vehicle body. The outward airflow flows in a direction that is toward an outer side in the vehicle widthwise direction and toward a rear side of the vehicle. The controller is configured to control the outward airflow generators.

摘要： An airflow adjusting apparatus to be provided in a vehicle includes an airflow ejector. The vehicle includes a wheel and a wheel housing including a cavity. The cavity is opened downward and laterally outward of a vehicle body of the vehicle, and houses a portion of the wheel. The airflow ejector is provided, in the cavity, on a front side of the vehicle relative to the wheel. The airflow ejector is configured to eject an airflow that forms a turbulence boundary layer adjacent to a surface of the wheel on a vehicle-widthwise inner side.
