Abstract

This paper presents a comparison between results of the theoretical and experimental researches carried out on models of greenhouses for vegetables and flowers, placed on the ground or on rooftops of buildings. Theoretical research has been achieved with ANSYS 15.0 software based on finite element method and experimental researches has taken place in the wind tunnel. In both cases, there were used five models of greenhouses were, with similar sizes that differ by the number of slopes of the roof (2 or 4) and by the angles between these slopes. Airflow velocities were identical and based on the pushing forces obtained witch which can be calculated as the coefficients of aerodynamic resistance specific for each researched model.
