The age-of-air concept can be used to assess the ventilation efficiency of an agricultural facility. However, experimental research has been limited due to the indirect method of using unstable tracer-gas and limited instrument. To overcome limitations and increase applicability, CFD technique was employed from established methodology by user-defined functions. A three-dimensional chamber was designed...
Limited measurement points and unpredictable airflows, as well as uncontrollable weather conditions, make conducting field experiments to study ventilation in broiler houses very difficult. Simulations using computational fluid dynamics (CFD) are often used to overcome the above mentioned limitation. In this study, airflow, internal air temperature distribution and ventilation efficiency of a conventional...
