- Abstract
Experimental analysis of air velocity and temperature distribution in poultry houses is laborious, especially for large scale houses. Enhanced broiler yield can be obtained when the house is suitably ventilated. Therefore, efficient prediction tools would be vital. Computational fluid dynamics (CFD) provides detailed data on indoor flow patterns, air velocity and temperature distribution in poultry houses giving promising outlooks as an efficient and cost-effective tool to establish optimum ventilation systems. This work focused on evaluation and numerical analysis of the influence of differential pressure (20, 30 and 40 Pa) and fan activation scenarios on indoor air velocity and temperature distribution in a poultry house. Results showed that air velocity tends to be maximum toward the centre of the cross-section of the house and minimum near the floor next to the side walls. Furthermore, it is elucidated that considerable thermal discomfort for chickens is likely due to temperature variation at the proximity to the exhaust fans. Based on the evaluations of pressure variation on the air velocity distribution, quick estimation of the air velocity can be obtained in the zones occupied bychickens. Generally speaking, numerical computation of the equations dominating the poultry house leads to desirable control model of the ventilation and aeration. This would be vital in decision making and economical management of the house.
