“…Traditionally, in agricultural engineering, (greenhouses and livestock buildings), the turbulence models commonly used were: standard k-ε, k-ε RNG, k-ε realizable and Reynolds Stress Model (RSM). In this paper, the standard k-ε model described by [26] was used, also considering that [18] also used it in their CFD simulations in a cross-mechanical ventilated poultry farm. This model is widely used in engineering for agricultural applications such as the modeling of poultry farms [18][19][20], because it is considered robust and reasonably accurate.…”

“…For laying hens, [20] studied a mechanical ventilated building using the commercial code CFD FLUENT [22]. Similarly, [18] studied a transversal, mechanically ventilated broiler farm with the same commercial code. However, they only used three measurement points in a single mobile support that had to be changed by an operator.…”

Exploring Ventilation Efficiency in Poultry Buildings: The Validation of Computational Fluid Dynamics (CFD) in a Cross-Mechanically Ventilated Broiler Farm

Broiler production in modern poultry farms commonly uses mechanical ventilation systems. This mechanical ventilation requires an amount of electric energy and a high level of investment in technology. Nevertheless, broiler production is affected by periodic problems of mortality because of thermal stress, thus being crucial to explore the ventilation efficiency. In this article, we analyze a cross-mechanical ventilation system focusing on air velocity distribution. In this way, two methodologies were used to explore indoor environment in livestock buildings: Computational Fluid Dynamics (CFD) simulations and direct measurements for verification and validation (V&V) of CFD. In this study, a validation model using a Generalized Linear Model (GLM) was conducted to compare these methodologies. The results showed that both methodologies were similar in results: the average of air velocities values were 0.60 ± 0.56 m s for direct measurements. In conclusion, the air velocity was not affected OPEN ACCESSEnergies 2013, 6 2606 by the methodology (CFD or direct measurements), and the CFD simulations were therefore validated to analyze indoor environment of poultry farms and its operations. A better knowledge of the indoor environment may contribute to reduce the demand of electric energy, increasing benefits and improving the thermal comfort of broilers.
