Three-dimensional photon migration through voidlike regions and channels.
Steady-state form of the Boltzmann transport equation is solved for the investigation of photon propagation through three-dimensional regions and channels that contain a photon absorption and scattering-free fluid. Transport and diffusion solutions are obtained by a finite-element-spherical harmonics radiation transport method. Results calculated with two theories are presented in order to show the influence of voidlike regions and channels on the transport of photons.
