The Spherical Harmonics Discrete Ordinate Method for Three-Dimensional Atmospheric Radiative Transfer
A new algorithm for modeling radiative transfer in inhomogeneous three-dimensional media is described. The spherical harmonics discrete ordinate method uses a spherical harmonic angular representation to reduce memory use and time computing the source function. The radiative transfer equation is integrated along discrete ordinates through a spatial grid to model the streaming of radiation. An a...
متن کاملRelativistic Radiative Transfer for Spherical Flows
We present a new complete set of Lagrangian relativistic hydrodynamical equations describing the transfer of energy and momentum between a standard fluid and a radiation fluid in a general non-stationary spherical flow. The new set of equations has been derived for a particular application to the study of the cosmological Quark–Hadron transition but can also be used in other contexts.
متن کاملNumerically stable algorithm for discrete-ordinate-method radiative transfer in multiple scattering and emitting layered media.
We summarize an advanced, thoroughly documented, and quite general purpose discrete ordinate algorithm for time-independent transfer calculations in vertically inhomogeneous, nonisothermal, plane-parallel media. Atmospheric applications ranging from the UV to the radar region of the electromagnetic spectrum are possible. The physical processes included are thermal emission, scattering, absorpti...
متن کاملTwo-dimensional Transient Radiative Heat Transfer Using Discrete Ordinates Method
The S-N discrete ordinates (DO) method is developed for the first time to solve transient radiative heat transfer in a two-dimensional rectangular enclosure with absorbing, emitting, and anisotropically scattering medium subject to diffuse and/or collimated laser irradiation. The transient DO method is used to solve several example problems and compared with the existing results and the Monte C...
متن کاملMulti-dimensional simulations of radiative transfer in Type Ia supernovae
A three-dimensional Monte Carlo code for modelling radiation transport in Type Ia supernovae is described. In addition to tracking Monte Carlo quanta to follow the emission, scattering and deposition of radiative energy, a scheme involving volumebased Monte Carlo estimators is used to allow properties of the emergent radiation field to be extracted for specific viewing angles in a multi-dimensi...
