Numerical Investigation of Aerodynamic Behaviors Inside and Outside a Tunnel Greenhouse
Main Article Content
Abstract
The study of greenhouse microclimates presents a significant challenge in the field of scientific research. Variations in aerodynamic parameters both inside and outside the greenhouse are of great importance, as they are associated with changes in air energy and motion simultaneously. However, these sensitive parameters have not been emphasized in the literature as much as temperature, humidity, and carbon dioxide concentration inside greenhouses. Variations in pressure, as well as drag and lift coefficients, can be significantly influenced by external factors such as air velocity and solar radiation intensity.
A computational fluid dynamics (CFD) study is conducted in this work, utilizing Fluent software for post-processing. The analysis is based on the Navier-Stokes fluid dynamics equations, which are solved using the finite volume method and incorporate the Large Eddy Simulation (LES) Smagorinsky turbulence model. The study focuses on the development of aerodynamic coefficient parameters both inside and outside the greenhouse, which can significantly impact the materials used in greenhouse construction, such as polyethylene or Plexiglas coverings, and iron or aluminum framing.
