Análise do comportamento dos ventos para o projeto de uma estrutura sustentável no Pecém-CE

Abstract

In a society increasingly concerned with sustainability and the minimization of impacts on the environment, it becomes attractive the design of a sustainable structure, maximizing natural lighting and optimizing the use of abundant winds of the region. In partnership with the UFC’s Architecture and Urbanism Department and ASTEF Foundation to conduct research related to the Energia Pecém it became necessary the knowledge of Mechanical Engineering and Fluid Dynamics to perform computer fluid simulations on the wind. Enhancing natural flow of winds in the structure decreases the need of environment refrigeration, reducing the consumption of electricity and turning it a sustainable structure. It was used the Ansys-CFX software to perform computer simulations predicting the behaviour of winds in the proposed structure. It was also used 2D and 3D modelling software, AutoCAD and SolidWorks, to adapt the models for simulation. Data on the direction and speed of the region's winds were used to make computer simulations as possible consistent with reality. Preliminary simulations were performed on the land, specific structural elements and simulations on complete structures to finish with the calculation for the average speed for the wind flow in the proposed structure.
