Wave-Scattering processes: path-integrals designed for the numerical handling of complex geometries
Jérémi Dauchet, Julien Charon, Laurent Brunel +10
Relying on Feynman-Kac path-integral methodology, we present a new statistical perspective on wave single-scattering by complex three-dimensional objects. The approach is implement…
Convergence issues in derivatives of Monte Carlo null-collision integral formulations: a solution
J-M Tregan, S. Blanco, J. Dauchet +5
When a Monte Carlo algorithm is used to evaluate a physical observable A, it is possible to slightly modify the algorithm so that it evaluates simultaneously A and the derivatives…
Longwave radiative analysis of cloudy scattering atmospheres using a Net Exchange Formulation
V. Eymet, J. L. Dufresne, P. Ricchiazzi +1
The Net Exchange Formulation (NEF) is an alternative to the usual radiative transfer equation. It was proposed in 1967 by Green [1] for atmospheric sciences and by Hottel [2] for e…
A boundary-based net-exchange Monte Carlo method for absorbing and scattering thick media
V. Eymet, R. Fournier, S. Blanco +1
A boundary-based net-exchange Monte Carlo method was introduced in [1] that allows to bypass the difficulties encountered by standard Monte Carlo algorithms in the limit of optical…
Path-tracing Monte Carlo Library for 3D Radiative Transfer in Highly Resolved Cloudy Atmospheres
Najda Villefranque, Fleur Couvreux, Richard Fournier +5
Interactions between clouds and radiation are at the root of many difficulties in numerically predicting future weather and climate and in retrieving the state of the atmosphere fr…
Implementation of the force term in half-range lattice Boltzmann models
Victor E. Ambrus, Victor Sofonea, Richard Fournier +1
In the frame of the Boltzmann equation, wall-bounded flows of rarefied gases require the implementation of boundary conditions at the kinetic level. Such boundary conditions induce…
