EOLIOS’ in-depth study has determined the wind potential under a roof with an aerodynamic profile.
The objective of such a project is the control of the particular aeraulic phenomena induced by the presence of numerous beams, recirculation zones, as well as the evaluation of the different optimization criteria in order to have the highest wind potential inside the building.
The CFD studies allowed to visualize the different aeraulic phenomena for different wind orientations, which allowed the optimization of the geometry in order to have the best possible performance of the wind turbine.
The creation of the model of the plant was carried out by taking into account the topology of the site with a great precision in order to be able to capture at most the evolution of the air flows. This digital twin takes up precisely the different sets of beams, the air volumes as well as the surrounding buildings.
This very marked precision for the realization of the numerical twin is translated into a flagrant gain on the veracity and the relevance of the results obtained during the CFD simulation.
The first CFD simulations of the external aeraulics have highlighted different interesting phenomena that could allow the increase of the wind potential. The restriction of the passage section of the wind at the rear of the building allows the creation of a Venturi effect, therefore a local increase in speed.
Following this study, Eolios was able to propose different designs respecting the different architectural challenges. These conclusions gave rise to in-depth work with the design teams, in order to accentuate and make the best use of this local increase in speed.
The objective of the study is to evaluate the relevance of implanting, or not, wind turbines within this building without impacting the overall architecture of the building. The use of CFD allows to simulate a large number of prototypes, in a short time, in order to quickly gather information for the optimization of the placement of the wind turbines as well as the optimization of the design in order to increase their efficiency.
This dynamic CFD study in order to set up and optimize the performance of wind turbines is part of a policy of development of sustainable energy. Minimizing the environmental impact as well as the energy consumption of buildings is at the heart of Eolios Ingénierie’s areas of interest.
