Lunar Computed Surface Radiation (CSR)
here for PDF presentation)
The Lunar-shine (Lunar IR environment) is a directionally dependent
surface flux because the temperature of the Lunar surface varies
largely. This directional dependence is modeled by the Space 3D Thermal
(commercial TSS) Lunar Computed Surface Radiation (Lunar CSR). In the
ray-tracing Lunar CSR method, the ray energy for each individual ray
depends on the where the ray was emitted from the lunar surface. This
method accounts for the variable directionally dependent Lunar IR
environment as shown.
Using the Lunar CSR model:
Within the Orbit application, specify the Moon on the Planet/Solar Data
form. Check ‘Range’ for the planet source, then specify the minimum and
maximum flux values.
Using Mesh and ConCap for solid to
Radiation Surface Modeling
Connecting solid elements generated
within the Mesh application to radiation surfaces can now easily be
done. This can be very useful in modeling blankets, and for performing
radiation analysis on an enclosure without having to carry along the
solid elements within it. When the conductor network is output from
ConCap, a Sinda/Fluint SYMBOL will be used (e*) in the conductor values
between the solid elements and the radiation surfaces. This will allow
the user to easily change the conductor values.
Using the Solid to Radiation Surface
- Load your Geometry model into Mesh, and mesh the desired enclosure(s).
When you output from Mesh, specify ‘solid to radiation surface list’ and
‘combined solid/surface Geometry file’
- When launching ConCap, specify the combined solid/surface geometry
file and the solid to surface radiation list. Go to Special Functions,
and select ‘Connect Solid Elements to Radiation Surfaces’. You can
specify an e* and other parameters on this form.
- You will now have the conductor network which can be output to a Sinda/Fluint
deck from ConCap.
