Computational fluid dynamics simulation for minimum pipe-ventilation system inside broiler building in winter season [electronic resource].

Includes references.

Increasing broiler performance and its productivity during winter season is the main purpose for all researchers. The ideal temperature for the best weight gain andfeed efficiency varies depending on birds age from 33-21 °C. Accordingly, the ventilation management has become one of the most important means of adapting and maintain the inside air temperature. The external air temperature in South Korea where the experiments were done is decreasing during winter season up to -20 °C. Under this condition from low air temperature, minimum ventilation must be provided. 3D-CFD mode/for broiler house with pipe ventilation system was designed to reach the required ventilation rate, air temperature, thermal uniformity and stability during winter season. To test this ventilation system under real conditions, computational fluid dynamic simulation was used to overcome the field experiments limitations. Field experiment aim to validate the conventional case was performed and the designed case was upgraded accordingly. The upgraded pipe ventilation system efficiency for reducing the Ammonia concentration in broiler zone was also examined. From the data analyzed, the upgraded case achieved suitable ventilation rate, air temperature distribution and Ammonia concentration reduction.
