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). A flow optimiser (203) diverts a section of airflow close to the apex (200) into the region (205), downstream of the apex. This section of diverted airflow is turned away from the local airflow direction towards the surface of the roof (201), downstream of the apex. This reduces the boundary layer separation and turbulence downstream of the apex (200), which reduces energy loss associated with sub-optimal static pressure recovery downstream of the apex (200), and thus increases the discharge coefficient of the system. |
