Discrete-ordinates solution of short-pulsed laser transport in two-dimensional turbid media.
The discrete-ordinates method is formulated to solve transient radiative transfer with the incorporation of a transient term in the transfer equation in two-dimensional rectangular enclosures containing absorbing, emitting, and anisotropically scattering media subject to diffuse and/or collimated laser irradiation. The governing equations resulting from the discrete-ordinates discretization of ...
متن کاملRadiative transfer in a spherical, emitting, absorbing and anisotropically scattering medium
The atmospheres of planets (including Earth) and the outer layers of stars have often been treated in radiative transfer as plane-parallel media, instead of spherical shells, which can lead to inaccuracy, e.g. limb darkening. We give an exact solution of the radiative transfer specific intensity at all points and directions in a finite spherical medium having arbitrary radial spectral distribut...
متن کاملSome Approximations to the Radiative Transfer Equation and Their Applications
To my parents, Laiping Sheng and Chengai Shi, who offered me unconditional love and support all the way since the beginning of my studies. This brief dedication is not enough room to express my gratitude that they are my parents. ii ACKNOWLEDGEMENTS I would like to thank several people for their help making this thesis possible. First and foremost, my greatest thankfulness goes to my advisor, P...
متن کاملExact solution of the characteristic equation for transfer in the anisotropically scattering and absorbing medium.
A special form of anisotropic scattering phase function is shown to provide an exact solution of the characteristic equation for radiation transfer at depth within a scattering and absorbing medium. The solution is the Henyey-Greenstein function, the degree of extension of which depends on the albedo for single scattering and on the parameter of the phase function. Good applicability of the for...
متن کاملEquivalent isotropic scattering formulation for transient short-pulse radiative transfer in anisotropic scattering planar media.
An isotropic scaling formulation is evaluated for transient radiative transfer in a one-dimensional planar slab subject to collimated and/or diffuse irradiation. The Monte Carlo method is used to implement the equivalent scattering and exact simulations of the transient short-pulse radiation transport through forward and backward anisotropic scattering planar media. The scaled equivalent isotro...
