Radiative Transfer Modeling of Simulation and Observational Data [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractRadiative Transfer (RT) is considered to be one of the four Grand Challenges in Computational Astrophysics aside of Astrophysical Fluid Dynamics, N-Body Problems in Astrophysics, and Relativistic Astrophysics. The high dimensionality (7D instead of 4D for MHD) and the underlying integro-differential transport equation have forced coders to ...

Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Simulation of Radiative Transfer Within X-ray Microcalorimeter Absorbers
Journal of Low Temperature Physics, 2022 AbstractWe present Monte Carlo simulations of radiative transfer within the absorbers of X-ray microcalorimeters, utilizing a numerical model for the photon propagation and photon absorption process within the absorber structure. In our model, we include effects of Compton scattering off bound electrons and fluorescence.

Fast reconstruction of hyperspectral radiative transfer simulations by using small spectral subsets: application to the oxygen A band [PDF]
Atmospheric Measurement Techniques, 2014 Hyperspectral radiative transfer simulations are a versatile tool in remote sensing but can pose a major computational burden. We describe a simple method to construct hyperspectral simulation results by using only a small spectral subsample of the ...
