Analysis of Airflow Uniformity in Pig Nurseries Using Duct Ventilation in Northeast China_prova_word
No full textThe problem of uneven ventilation in pig houses must be solved to effectively improve the winter environmental quality of pig nurseries in cold regions. In this study, the airflow field and airflow uneven coefficients of pig nurseries with duct ventilation were simulated and calculated using computational fluid dynamics, and compared with pig nurseries with different duct diameters, inlet and outlet air velocities and air supply angles. The average relative error between the simulated and measured values was {| class="formulaSCP" style="width: 100%; text-align: center;" |- | 12\% |} . Comparison of simulation results and airflow uneven coefficients showed that the airflow uneven coefficients of the fences were reduced, and the airflow field was uniformly distributed with a duct diameter of 0.3 m , inlet and outlet air velocities of 1.5 and {| class="formulaSCP" style="width: 100%; text-align: center;" |- | 2.0\, m/s |} , respectively, and an air supply angle of {| class="formulaSCP" style="width: 100%; text-align: center;" |- | {45}^{\circ } |} . These improvements resulted in a more homogeneous ventilation, which led to more uniform ventilation and contributed to discharging dirty air outdoors. Then the test pig nursery was modified based on the simulation and analysis results. Difference analyses were carried out between the control and the test pig nurseries. Comparative analyses showed the differences between the test data and the monitoring data were smaller, and the duct ventilation was more uniform, which was suitable for the healthy growth of piglets
