The influence of buildings to wind velocity and direction

This research aims to study the property of wind flow through the building of Science and Technology, Rajamangala University of Technology Thanyaburi to develop proper wind turbine design which install on the building. Ultrasonic Anemometer 3D is an instrument which used in this study. It was installed on the top of the building of Science and Technology. The sampling interval of data collecting is 6 seconds. The study period was from February 2013 to January 2014. The result shown the wind flow was parallel to the ground by average velocity of 5 m/s. The major wind direction affect by the monsoon seasonal wind. In the raining season (May to October) the wind flow is same direction as Southwest monsoon wind. In the winter season (October to February) the wind flow is same direction as Northeast monsoon wind and in the summer season (February to May) the wind flow is in the transition period of Northeast monsoon to Southwest monsoon. Based on the result wind turbine design could be vertical axis wind turbine which has small size and light weight to fit with low wind velocity at any wind direction.
