Methods to Reduce the Risk to Wind Action of the Fixing Systems of Sollar Collectors

摘要

The interest in the non-conventional energy resources, a consequence ofthe severe restrictions imposed towards pollution of any kind, arises again the interest inusing solar collectors. Implanting them on the terraces of new or existent homeresidencies, or any kind of other buildings, means to solve a sum of engineeringproblems, among them being also the stages of safely designing the plane panels forcollectors and the sustaining skeleton, made in steel as well as the fixing systems adoptedfor the interface with the building itself. The necessity of considering the maximum windspeeds actions along other dynamic effects of its turbulence is the result of a many yearsexperience, specially if one must also think in terms of efficiency and costs both forconstruction and exploitation.The pattern of the wind flow field suffers intricate alterations in the proximity ofthese collectors placed in the vicinity of the building surface and, in these situations, it iscommon to test the models at a reduced scale in wind tunnels with atmospheric boundarylayers. The experimental study presented in this paper was undertaken in the Laboratory ofAerodynamics of the Faculty of Construction and Building Services in Ia?i and it revealsthe results and the conclusions drawn from the analysis of the wind flow over a row ofcollectors differently arranged in order to evaluate the wind pressure coefficients used indesign.
