Preface
Two essential components of solar energy which are derivable from
the sun-radiant light (passive solar power) and heat (active solar
powers) have been harnessed for decades using a range of
continuously-evolving and cutting-edge technologies.
Such technologies include solar heating, solar photovoltaics, solar
thermal energy, solar architecture and photo emitters.
Recently, there has been active research in solar energy resources
due to improvements in solar panel geometry, photo-cell materials,
glazing and panel orientation. Equally, more rigorous methods of
modeling inter-reflections within curvilinear surfaces are now being
evaluated for simplified analytical evaluations.
Therefore, this book, Solar Radiation Applications, presents the
outcomes of selective and classic works on the optimization of these
essential fields in active solar energy research.

1. Introduction
Curved surfaces have not been thoroughly considered in radiative transfer analysis mainly
due to the difficulties arising from the integration process and perhaps because of the lack of
spatial vision of researchers. When dealing with them, application of the iterative method or
direct calculation through integration does not provide with an exact solution, so that only
approximate expressions or tables are given for a very limited number of forms [1]. In this
way, a vast repertoire of significant shapes remains neglected and energy waste is evident. For
this reason, further research on the matter, starting from a different approach was considered
worth doing.
In previous researches from the authors, form factor calculation has been undertaken for
several types of emitters. In all cases, geometric properties of those, revealed as the most
powerful tool that shapes radiant interchange [3,4,5,6]. This included mainly rectangular
shapes, plane forms and the volumes that can be composed with such primary geometries.
Following the same approach to radiative transfer through the basic understanding of the
spatial and geometric properties of volumes, in this chapter new form factors derived from a
combination of curvilinear surfaces are hereby presented. Starting from the properties of the
sphere and with simple calculus, new laws are devised, which enable the authors to discover
a set of configuration factors for caps and various segments of the sphere. The procedure is
subsequently extended to the paraboloid, the ellipsoid or the cone, useful in issues such as
rocket nozzle design and organic shapes contained in human physique. Appropriate combi‐
nation of the said forms with truncated cones, produces highly articulate shapes, which
