- W4382062062 abstract "Maintaining normalized microclimate in poultry farming is one of the basic factors. It is the quality indicators of the air parameters that ultimately determine the quality of the final product. Keeping poultry requires a lot of effort and technological solutions. In this regard the authors have made improvements of the microclimate system in the air environment of the poultry house by installing exhaust fans on the side wall, in a total of 8 pcs, and 2 pcs. on the end wall. A powerful tool for predicting the airflow patterns in the poultry house is modelling. An alternative to experimental studies is Computational Fluid Dynamics (CFD) with ANSYS Fluent. The CFD model was performed on the Navier-Stokes equations for convective flows. The calculations used the Spalart-Allmaras turbulence model and the Discrete Ordinates radiation model. CFD modeling was performed at an air flow rate of 21.5 kg·s-1. The outside air temperature is assumed to be 2 °C and the thermal radiation parameter is entered. In poultry houses, the poultry, when kept on the floor, is a source of heat and is + 41 °C. Heating system is not provided. To remove air, exhaust fans of the Munters EM50 1.5Hp type are used. Fans are mounted on the side wall in the amount of 4 units. and 1 on the end wall. Supply valves Wlotpowietrza 3000-VFG with a total of 80 pcs. Above the valves there are built-in spoilers at an angle of inclination from the vertical 75°. The results of the CFD modelling showed that the valves, located at a height of 210 mm from the ceiling, work efficiently. The pressure drop at the supply valves is 73.565 Pa. The air speed at the inlet of the supply valves is 11.45 m·s-1. The air speed at a height of 0.7 m from the floor level varies within 0.86 m·s-1, the temperature is 14.12 °C." @default.
