Development and validation of cfd model for compost barn with artificial ventilation

Computer simulation can provide reliable information about fluid flow behavior, including ventilation, in animal production systems. The ventilation system is essential for thermal conditioning, as it favors comfort and enhance productivity. objective of this study was to develop validate a CFD (Computational Fluid Dynamics) model analyze the compost barn. A mesh with greater refinement used near air inlet outlet floor, that is, these regions number cells larger, which makes denser mesh. For validation, data on velocity were collected barn compare results simulation. Dead zones identified barn, there an increase average at outlet, temperatures found below optimal recommended by literature. However, adjusted showed good fit values measured, indicating tool predict behavior velocity. In addition, detection dead inside demonstrates need supplementary system.
