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.
