Factors affecting the transverse air flow when the air moving through the building and moving through a section of a wind turbine rotor. There are many factors, such as environment, buildings, wind speed, wind direction, these factors affect the performance of the wind turbine research is to analyze the flow of air by calculation program with computer fluid dynamics (Computational. Fluid Dynamics, CFDesign V.9) analysis of the transverse air flow on the performance of wind turbine size 5KW wind speed at 10 m / s moving through the building of a training center for energy, petroleum, military personnel (a, B,. C, D) found that wind speed the northeast (NE) moving through the exhibition building (C) to change the shutter speed winds minimal position WT3 dropped 1.468% and the South west (SW) moving through the building, catering. (a) to change the shutter speed winds minimal position WT3 fell 1.2796% and when passing in front of the rotor of a wind turbine at the WT1, WT2, WT3 find a position (2d) 12, (3d) 18, and (. 4d) 24 meters long (4d) 24 meter wind turbine minimal impact on performance.
