Numerical Simulation of Polarized Light and Temperature in a Stratified Atmosphere with a Slowly Varying Refractive Index
Olivier Pironneau
This article is an attempt to elucidate the effect of a slowly varying refractive index on the temperature in a stratified atmosphere, with a particular focus on greenhouse gases s…
Numerical Simulation of Polarized Light and Temperature with a Refractive Interface
Olivier Pironneau
In this article we propose a numerical algorithm to compute the intensity and polarization of a polychromatic electromagnetic radiation crossing a medium with graded refractive ind…
Optimal Quota for a Multi-species Fishing Models
Olivier Pironneau
A Stochastic Control Problem can be solved by Dynamic Programming or Distributed Optimal Control with the Kolmogorov equation for the probability density of the Markov process of t…
Simulation of the 3D Radiative Transfer with Anisotropic Scattering for Convective Trails
Olivier Pironneau, Pierre-Henri Tournier
The integro-differential formulation of the RTE and its solution by iterations on the source has been extended here to handle anisotropic scattering. The iterative part of the meth…
Reflective Conditions for Radiative Transfer in Integral Form with H-Matrices
Olivier Pironneau, Pierre-Henri Tournier
In a recent article the authors showed that the radiative Transfer equations with multiple frequencies and scattering can be formulated as a nonlinear integral system. In the prese…
Radiative Transfer in a Fluid
Francois Golse, Olivier Pironneau
We study the Radiative Transfer equations coupled with the time dependent temperature equation of a fluid: existence, uniqueness, a maximum principle are established. A short numer…
