|Abstract: ||In this study, formulae for predicting projected area
factors and view factors of individual body parts of
standing and sedentary humans for detailed radiation
analysis were developed. For this purpose, detailed
geometry models of the human body were generated
representing an average subject with a height of 1.75
m and a DuBois’ area of 1.83 m2. Thermal analysis
software incorporating advanced, voxel-based ray
tracing techniques and regression analysis were
deployed to model the local projected area factors of
humans exposed to direct and diffuse solar radiation.
A method was developed to predict view factors of
individual body parts based on the projected area
factor calculations. This technique makes it possible
to predict view factors between individual body parts
and surrounding surfaces for almost any arbitrary
geometrical configurations of the radiation envelope.
The predicted view factors were validated and
showed good agreement with experimental data
available in the literature.|
