(Gnu Radiation Computer Aided Modeler)
Welcome
GnuRad allows a user to model a variety of radiation heat transfer
problems without having to write a computer program. GnuRad can model
something simple as energy radiating from a plane surface, or something
complex where the model is a series of connected enclosures containing
a participating medium. The types of models that GnuRad can run is
quite extensive, currently limited to only orthogonal plane gray
surfaces with a medium having isotropic scattering. Some examples of
what GnuRad can model are:
- The radiant energy which is absorbed by a furnace wall
- Radiant energy distribution of a room with windows and a fireplace
- The radiation exchange factor
- The temperature distribution in a participating medium based on
radiant energy
GnuRad is a computer program which simulates the radiation heat
transfer in an enclosure or series of connected enclosures. The basic
enclosure is 'box' shaped (regular parallelepiped) having arbitrary
dimensions and containing a medium. Depending on the requirements of
the model, boxes can be joined together, walls can be removed, and the
medium can be participating or non-participating.
GnuRad is a direct physical model using the Monte Carlo technique
for photon bundle direction and initial position. Details of the Monte
Carlo technique can be found in several of the books listed in the
Reference section of this document.
GnuRad is written in C++ using object oriented programming
practices. GnuRad is protected by the GNU public license ( 2.0 and/or
higher). Roughly this means, the source code and user manual of GnuRad
are free to be copied or modified as long as any changes or
enhancements continue to be free. This philosophy will allow GnuRad to
continue to grow in options and features.
