Abstract
An airflow control device 10 in an embodiment includes: a vortex shedding structure portion 20 discharging an airflow flowing on a surface in a flow direction as a vortex flow; and a first electrode 40 and a second electrode 41 disposed on a downstream side of the vortex shedding structure portion 20 via a dielectric. By applying a voltage between the first electrode 40 and the second electrode 41, flow of the airflow on the downstream side of the vortex shedding structure portion 20 is controlled.
