摘要： The types of greenhouses in agricultural parks are complex and diverse, with different shapes and sizes, and are densely distributed. The study of the greenhouse wind environment at the park scale can better reflect the influence of wind-induced interference effects between greenhouses. This study integrated an in-situ test with computational fluid dynamics (CFD) to investigate the wind environment distribution of an agricultural park consisting of multi-type greenhouses. The wind environment of the park is affected by the shielding effect and has obvious differences in various wind angles. Moreover, there is Venturi effect between greenhouses, and the difference in the width of the passages will affect the airflow speed. Building upon these characteristics, this study established arched greenhouse models with 20 m span greenhouses with ridge heights of 5.5 m, 6.5 m, and 7.5 m, as well as 8 m span ridge heights of 3.0 m, 3.4 m, and 3.8 m. For 20 m span greenhouses, a spacing of 2.5 m is recommended, while for the 8 m span greenhouses, a spacing of not less than 1.5 m is found to be conducive to good ventilation. These results provide valuable insights for the planning and design of agricultural facility complexes.
