Investigation of an Improved Side Ventilation System in a Poultry House Using CFD

Abstract

One of the main factors in the poultry house is maintaining a standardized microclimate. The quality of the product output in the final result depends precisely on the quality indicators of the air parameters. Poultry during its maintenance requires significant efforts and technological solutions. In this regard, authors improved microclimate system in air environment of the poultry house by installing exhaust fans on the side wall in a total number of 8 units. CFD modeling using ANSYS Fluent is a powerful tool for predicting the air flow scheme in a poultry house and is considered an alternative to experimental studies. Based on the obtained results of CFD modeling, it was established that the valves located at a height of 330 mm from the ceiling work most efficiently. Pressure drop for the inlet valves is 45.85 Pa. Air velocity at the inlet of the supply valves is equal to 9.17 m/s. Air velocity at a height of 0.7 m from the floor level varies within 0.57 m/s, the temperature is 9.91 °С.

Usage of CFD for research on lateral ventilation system in poultry house

“…This gave an opportunity to reduce the air flow disturbance near the exhaust fans and in certain areas of the poultry house. The negative impact of such air disturbance is presented in [13]. One exhaust fan is located on the end wall of the poultry house along the upper line.…”

“…In previous investigations [13] the supply valves, ranging from 11 to 40, were located at a height of 0.81 m from the overlap, and the first 10 at a height of 0.21 m. Taking into account the previous recommendations, all the valves are raised to a height of 0.21 m from the ceiling. There was noted also inefficiency of operation of the first supply valves on the right and left sides, which are located at the exhaust fans.…”
