Чисельне моделювання як метод дослідження та вдосконалення бокової системи вентиляції в пташнику з традиційним розташуванням витяжних вентиляторів

Abstract

In order to ensure a normalized and uniform internal environment in the poultry house, for large productions, new ventilation systems are needed. As part of this study, numerical simulations of the lateral ventilation system in the poultry house during the winter period of the year were performed. The result is the fields of velocities, current lines and pressures in the poultry house in a 3D setting. It was found that the supply valves located at a height of 200 mm from the floor work much more efficiently than in the traditional setting at a height of 400 mm. Installation of walls on the inside of the poultry house frame, as well as reducing the height of the floor improve the aerodynamics in the poultry house.
