Abstract

This study addresses the challenges of inadequate air circulation and excessive internal temperatures in greenhouses within the Yangtze River Delta region. The research uses experimental methods and computational fluid dynamics (CFD). Findings revealed that introducing 90° side windows significantly improved airflow and temperature distribution, whereas 45° side windows had minimal impact. Adding layers improved cooling performance at all measurement points. However, as the number of shading net layers increases, the cooling capacity decreases with each additional shade net layer. These findings offer a scientific basis for this region's greenhouse ventilation and shading nets using strategies for optimizing greenhouse environments.
