Abstract(s)
The Sun is the largest source of energy available and many studies for the development
of technologies capable of harnessing this energy are constantly being conducted.
Among the technologies developed are photovoltaic solar panels that have many
applications and among them are the autonomous solar lighting columns that have
been growing in popularity especially in urban and industrial environments. These
columns are installed in open regions and have their structure exposed to the
mechanical actions imposed by the wind, so they need to be correctly designed to
support them. There are aerodynamic variables that must be determined for the design
of these columns, especially the drag coefficient, a property linked to the geometry
of a body, which represents its interaction with a flowing fluid. Due to the complexity
of determining these variables, experimental methods are constantly used to obtain
these values. Classically, wind tunnel simulations are used for this purpose, but they
can be expensive and difficult to perform. Fluid dynamic computational analysis has
been widely applied to replace physical analysis. In this work, the drag coefficient of
an autonomous solar lighting column is determined by wind tunnel simulations and
computational analysis. With the obtained results, a comparison is made to verify
the fidelity of the data obtained by computational means when compared to those
obtained through the wind tunnel simulations.
