Description
Summary:Two different sets of data used to achieve this work were measured by fast- and slow-response devices, which located on the roof of building followed to College of Science, Mustansiriyah university. Wind speed data classified to calculate their frequencies and wind and wind rose. Wind direction prevailing is northeast and most frequencies are at less than 3 m/s. To improve these speeds, the internal boundary layer (IBL) height establishing over urban Baghdad city was estimated to satisfy the airflow characteristics before entering the city. The values of IBL height were calculated according to air stability classifications: unstable, neutral and stable. These values are lower at stable, graduate increase at neutral, and extreme increase at unstable conditions. However, the better performance of wind turbine operation over the surface of Baghdad city is suggested to be at the low level of 78 m.
