The aerodynamic study on ventilation of agricultural buildings has not been active because of
difficulties in conducting field experiment. An engineering approach like aerodynamic analysis should be
performed to design and manage the system systematically and scientifically. Moreover, this technology can
contribute greatly to the development of overall HVAC system of agricultural buildings suitable for seasonal
climates of Korea. This paper introduces the newest scientific and engineering technologies of aerodynamics
that can be used to improve or develop structural and ventilating designs. Typical technologies of aerodynamics
are large-sized wind tunnel, particle image velocimetry (PIV) technology, and computational fluid dynamics
(CFD).
