While livestock facilities in Korea have been changed larger and denser, breeding environment has been getting worse and the productivity of domestic animal have been decreased. It would be worse especially In the cold season because of the minimized ventilation rate to save energy cost. Therefore wet air cleaner can be used to enhance the rearing environment by removing noxious gases and dusts. But, it is difficult to analyze the internal air flow and the environmental factors by only field experiment. Therefore, aerodynamic computer simulation was used to upgrade ventilation system including arrangement of the wet air cleaner. To make simulation model accurately and actually, simplified pig models and tracer gas decay method were used. Accuracy of simulation model was enhanced by 4.4 % of errors compared with data of the field experiment. From the verified CFD model, internal ventilation system and its efficiency with wet air cleaner will be analyzed quantitatively as well as qualitatively.

Odor is one of the major nuisances in the environment. Especially, odor annoyance from livestock production is an increasing problem in communities in many countries. In order to reduce the odor inconvenience and establish good relations between livestock industry and surrounding communities, many studies on the odor dispersion, such as field experiment and diffusion simulation, have been investigated. Especially, CFD being used widely will be effective for aerodynamic analysis with consideration for various wind conditions as well as topographical conditions. Therefore the ultimate objective is to develop the aerodynamic model for predicting qualitative and quantitative diffusion of livestock odor, and in this study, phenomena and factors of livestock odor diffusion were investigated previously.
