Simulation and study of CFD-based greenhouse modeling

This paper constructs a three-dimensional model of a glass greenhouse and uses the RNG k−ε turbulence model to simulate the airflow and temperature distribution within the greenhouse, investigating the impact of plant canopies on temperature control. The results show that the presence of plant canopies significantly alters the airflow and temperature distribution within the greenhouse. The temperature rises faster in areas closer to the fan, while temperature changes are slower in areas farther away. By optimizing ventilation port design and plant layout, the temperature uniformity within the greenhouse can be effectively improved, creating a more suitable environment for crop growth. The study provides a theoretical basis for optimizing greenhouse ventilation structure and offers new insights for achieving precise greenhouse environment control.
