Numerical Simulation of Radiative Transfer

Radiative Transfer in Inhomogeneous Atmospheres - Numerical Results

The FN method is used to establish accurate numerical results for the albedo and the exit distribution of radiation relevant to an illuminated semi-infinite half space with an exponentially varying albedo for single scattering.

Radiative Transfer in 3D Numerical Simulations

We simulate convection near the solar surface, where the continuum optical depth is of order unity. Hence, to determine the radiative heating and cooling in the energy conservation equation, we must solve the radiative transfer equation (instead of using the diffusion or optically thin cooling approximations). A method efficient enough to calculate the radiation for thousands of time steps is n...

Numerical methods for multidimensional radiative transfer∗

This paper presents a continuous finite element method for solving the resonance line transfer problem in moving media. The algorithm is capable of dealing with three spatial dimensions, using hierarchically structured grids which are locally refined by means of duality-based a-posteriori error estimates. Application of the method to coherent isotropic scattering and complete redistribution giv...

Accurate numerical simulation of radiative heat transfer with application to crystal growth

We present an accurate and cost-effective numerical method to investigate thermomagnetic problems arising in crystal growth applications. The governing equations are the quasi-static, time-harmonic, axisymmetric Maxwell equations coupled with an energy conservation equation. Radiant energy transfer is modeled by an integral equation yielding a strongly nonlinear and non-local problem. Conformal...
