Impact of Fan Position and Speed Adjustments in Glass Greenhouse Environments

Abstract

In the context of the contemporary development of precision agriculture, glass greenhouses, as an important infrastructure for enhancing crop production efficiency and quality, have become a frontier area of agricultural science and technology innovation for the internal microenvironmental regulation, especially the optimization of airflow dynamics and temperature distribution. In this paper, the study is based on the three-dimensional turbulence model equations of Reynolds number and Darcy-Forkheimer law, and modeled the cases without and with crops, simulated their different wind velocity and temperature, generated the corresponding simulation diagrams and analyzed them, and the results show that changing the Wind velocity to 3m/s or changing the fan position to 1m is a better condition than that with Wind velocity of 2m/s and fan position of 1.3m. In this study, it was found that both variables, Wind velocity and fan position, could affect the growth of crops in glasshouse, excluding most of the factors.
