| 摘 要： | 肉鸭产业规模化程度越来越高、空间集聚日益明显,层叠式笼养是发展最为迅速的立体养殖模式。该文对层叠式笼养鸭舍内的温湿度、气流、CO_2及NH_3质量浓度进行测试,构建了鸭舍的CFD模型,开展温度场和气流场的环境模拟,并提出现有鸭舍气流组织形式的优化方案。研究结果表明,测试期间(2018-12-18 00:00-2018-12-22 00:00),鸭舍内气温11.35～20.68℃,舍内外平均温差10.86℃;舍内平均相对湿度70.27%,略高于舍外;舍内CO_2、NH_3平均质量浓度分别为3285、0.33 mg/m~3。模拟原有鸭舍的温度场和气流场,与实测结果进行对比,平均相对误差为6.59%～8.87%,说明该文所建模型的数值模拟与试验数据具有很好的一致性。进一步通过降低一侧通风小窗的高度来优化鸭舍的气流组织,模拟发现优化后模型的舍内温度范围为11.07～19.71℃,其温度波动范围较原模型有明显减小,降低了肉鸭对温度的应激效应;优化后模型北侧第1列底层、第3列中层、第5列上层的平均风速分别为0.34、0.34、0.31 m/s,较原模型更加均匀。通过该研究,可为同类型鸭舍合理规划设计与改善舍内环境质量提供理论依据。
