| 摘 要： | 以北方地区猪舍为研究对象,采用Fluent软件对5种不同窗口面积的猪舍内自然通风气流场进行三维稳态模拟,并对模拟结果与实测结果进行对比分析。结果表明,合理的窗地比和窗口长宽比决定了通风效果。针对该研究中的实际猪舍,窗地比为1：10的通风死角少,通风均匀性好;长宽比较小的气流滞留区小,通风效果好;窗地比相同的（即窗口面积相同）的情况下,窗口数量越多通风效果越好。模拟值与测量值有较好的一致性,最大相对误差为11.1%,平均相对误差为7.7%。因此可用Fluent软件模拟分析猪舍内气流流场,优化猪舍结构。

| Abstract: | With northern pig house as study objective,the 3-D numerical simulation of natural ventilation airflow field of five pig houses with different window area was done by using Fluent software,and the comparative analysis was carried out on simulation result and measured result.The results showed that the effect of ventilation was decided by the reasonable area ratio of window and earth and the ratio of length and width of window.According to this real pig house in experiment,there are the best uniformity of ventilation and the least area of having no ventilation by 1：10 of the area ratio of the window and earth in the pig houses,the smaller air retention zone by the smaller ratio of length and width of window,the better effect of ventilation;the results of simulation agree well with the results of measured,the max relative error and the average error was 11.1% and 7.7%,so the software of Fluent was proved effective in the numerical simulation of natural ventilation in the pig houses and the optimal design of pig houses＇ structure. |
