Wind Tunnel Consulting
In recent years we have identified the need to tackle the analytical study of wind effects and its interaction with structures in a specific way so that, deepen in the quantification of wind action and also in the study of confort conditions is allowed.
Designing increasingly slender, light and geometrically more complex structures, along with the need to study these structures during its construction process including its auxiliary means, makes the quantification of the wind action very difficult. Comfort inside and in the vicinity of these structures is also a complex and increasingly more important task in early stages of the project.
A very effective option to address these problems is to use computational tools as CFD (Computational Fluid Dynamics). With the addition of specialists technicians in this field it is posible to tackle the following studies:
Wind confort studies.
First, there is the possibility of modeling real wind situations in open and closed spaces and thus evaluate the comfort by controlling the average speed and gust and its probability of occurrence in the selected critical points, gateways, terraces, etc .. Secondly, there is the possibility of simulating climate conditions in open or closed spaces. Taking into account that you can set control devices in the analysis and that can be analyzed jointly radiation and convection, HVAC systems can be optimized.

Virtual wind tunnel.
The handling of this type of CFD allows the ability to conduct full-scale aerodynamic simulations.
With this type of study wind flow around full-scale models of buildings, bridges and other civil engineering works can be simulated. This analysis allows to study the impact of the presence of structure in the behavior of air not only (allowing, for example, volumetric rendering of turbulence or particle transport analysis pollution), but are also able to measure wind loads on structures, and obtain the pressure coefficient on their surfaces, providing both distributions: average pressure transient data and maximum and minimum peaks.
On the virtual wind tunnel analytical expressions can be entered to describe the wind profile or adjust the intensity of air turbulence at the entrance. This, combined with the ease of introduce virtually small changes in the geometries, can analyze at a minimun cost. Moreover, the virtual analysis goes beyond a mere alternative to the experimental wind tunnel and allows understanding why slight variations in design models drastically affect performance.
