Investigation of the lateral ventilation system in a poultry house using CFD

Abstract

Maintaining a normalised microclimate in a poultry house is one of the main factors. It is the quality indicators of air parameters that ultimately determine the quality of product output. Keeping poultry requires considerable efforts and technological solutions. In this regard, the purpose of the study is to improve the microclimate system in the poultry house by installing ventilation equipment on the side wall. A powerful tool for predicting the air flow pattern in a poultry house is Computational Fluid Dynamics (CFD) modelling using ANSYS Fluent. This is an alternative to experimental research. CFD modelling results have shown that the valves operate most efficiently at 330 mm from the ceiling. The pressure drop of the supply valves is 45.85 Pa. The air velocity at the inlet of the supply valves is 9.17 m/s. The air velocity at a height of 0.7 m from the floor level varies within 0.57 m/s, the temperature – 9.91°C
