The aerodynamic study on ventilation of agricultural buildings has not been conducted very actively while ventilation is considered as one of the most important factors for livestock as well as plant environmental control. Because of disadvantages of conducting field experiment, some indirect methods such as tracer gas, wind-buoyancy model, energy balance model, etc were performed, however, those methods could not precisely clarify the cause of locally poor internal environment of agricultural buildings. It indicated that aerodynamic analysis should be performed to systematically and scientifically design as well as manage the overall system. Moreover, using this technology, it is possible to develop optimum mutual system of agricultural buildings considering HVAC suitable for seasonal climates of Korea. Through this paper, wind tunnel that is one of the typical tools of aerodynamic study was introduced. It can be used for the studies on development of structural and ventilating designs while it has been actively used for the studies of Aerospace, Mechanical, Civil, and Architectural Engineering for last century. A multi-purposed large-sized wind tunnel was built at National Agricultural Mechanization Research Institute in Korea on October 24, 2000. Currently, it has been optimized for the aerodynamic study of agriculture such as boundary layers of wind speed, turbulence, power spectrum, etc.
