The greenhouse serves as an enclosed structure designed to create a conducive environment for agricultural productivity, irrespective of the challenges posed by seasonal variations. Recognizing the contemporary complexities in agricultural management, our research endeavors involve the development of a comprehensive numerical model and the establishment of an experimental setup to delve into the nuanced impact of mechanical ventilation. Specifically, the study investigates the influence of four different entrance velocity values on airflow dynamics within agricultural greenhouses. The results illuminate the direct correlation between inlet velocity and various crucial variables, including temperature distribution, velocity field distribution, DO irradiation distribution, and static pressure distribution. Notably, at Vint = 12 m.s-1, the maximum temperature remains below Tmax = 307 K, while at Vint = 3 m.s-1, it reaches Tmax = 327 K. This underscores the pivotal role of accurate modeling and control for the optimal management of agriculture in the central region of Tunisia, particularly in Sfax.
