Abstract: A roof 201 has an apex 200. A wind turbine 202 is positioned above the apex 200. Air flows through the gap 204 between the apex 200 and the turbine 202.

Abstract: An aerodynamic noise reduction device reduces aerodynamic noise originating from a separation region located downstream of a step portion protruding from a surface of an object placed in an airflow. Since the step portion protrudes from the surface of the object placed in the airflow, aerodynamic noise is generated from the airflow separation region located downstream of the step portion. However, by forming an air discharge vent at the step portion at a position near a point, in the separation region, where a Reynolds stress is at its maximum and by discharging air from the air discharge vent toward the point where the Reynolds stress is at its maximum, the velocity gradient in the separated shear layer in the separation region is mitigated to decrease the maximum value of the Reynolds stress. The aerodynamic noise is thus effectively reduced.
