Özet

An essential parameter for the design of a dairy barn is adequate ventilation. A well-ventilated barn benefits the environment and the animals by reducing stress and improving air quality. The aim of this study was to evaluate the spatial variability of environmental conditions in a free-stall dairy barn using computational fluid dynamics (CFD). Measurements of temperature and air velocity in the barn were made for comparison with the simulated results. The simulations were performed under steady-state conditions and considered the specific behavior of standing and lying cows and their distribution in the barn. The measured and predicted mean air temperatures in the barn were 21.50 ± 0.174 °C and 21.33 ± 0.213 °C, while the air velocities were 0.30 ± 0.196 m s-1 and 0.31 ± 0.197 m s-1, respectively. In conclusion, this study demonstrated that CFD is a valuable tool for evaluating the spatial variability of environmental conditions in dairy barns and can be used as an alternative technique for analyzing barn environments.
