Model reduction techniques for frequency averaging in radiative heat transfer
We study model reduction techniques for frequency averaging in radiative heat transfer. Especially, we employ proper orthogonal decomposition in combination with the method of snapshots to devise an automated a posteriori algorithm, which helps to reduce significantly the dimensionality for further simulations. The reliability of the surrogate models is tested and we compare the results with tw...
متن کاملCo-moving frame radiative transfer in spherical media with arbitrary velocity fields
Recently, with the advances in computational speed and availability there has been a growth in the number and resolution of fully 3-D hydrodynamical simulations. However, all of these simulations are purely hydrodynamical and there has been little attempt to include the effects of radiative transfer except in a purely phenomenological manner because the computational cost is too large even for ...
متن کاملMcSCIA: application of the Equivalence Theorem in a Monte Carlo radiative transfer model for spherical shell atmospheres
A new multiple-scattering Monte Carlo 3-D radiative transfer model named McSCIA (Monte Carlo for SCIAmachy) is presented. The backward technique is used to efficiently simulate narrow field of view instruments. The McSCIA algorithm has been formulated as a function of the Earth’s radius, and can thus perform simulations for both plane-parallel and spherical atmospheres. The latter geometry is e...
متن کاملRadiative transfer in a semitransparent hemispherical shell
Radiative transfer in a semitransparent hemispherical shell placed on an opaque surface is simple yet realistic representation of the heating process encountered in various materials processing applications ranging from metallurgical slag foaming to batch foams in glass melting to hollow bead fabrication. The objective of this paper is to develop fundamental understanding and predictive models ...
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.
