| Abstract: | The transient radiative transfer equation in a two
dimensional participating medium bounded by
diffusely emitting and reflecting boundaries, one
of the boundaries is irradiated with a short pulse
laser beam is solved using finite volume method.
In the proposed approach, intensity can directly
be evaluated by solving the governing transient
radiative transfer equation. The effects of optical
thickness, scattering albedo and wall emissivity
on the transmitted and reflected signals are
studied. The performance of two different spatial
schemes: STEP and CLAM are also been tested.
It is seen that the CLAM scheme gives results to
a greater accuracy and hence, correctly predict
the speed of photon whereas STEP scheme over
predicts the same. |
