Implicit Monte Carlo Methods for Three-Temperature Physics
The third method (ECIMC) treats the conduction explicitly and includes all of the conduction and coupling in the linearization of the transport equation. This is a good approximation when the conduction timescales are much longer than the radiation-transport timescales. We expect this to be the case for most problems because the conduction timescales are related to the electron thermal velocity...
متن کاملMonte Carlo and quasi-Monte Carlo methods
Monte Carlo is one of the most versatile and widely used numerical methods. Its convergence rate, O(N~^), is independent of dimension, which shows Monte Carlo to be very robust but also slow. This article presents an introduction to Monte Carlo methods for integration problems, including convergence theory, sampling methods and variance reduction techniques. Accelerated convergence for Monte Ca...
متن کاملFluctuating Hydrodynamics and Direct Simulation Monte Carlo
Thermodynamic fluctuations are significant at microscopic scales even when hydrodynamic transport models (i.e., Navier-Stokes equations) are still accurate; a well-known example is Rayleigh scattering, which makes the sky blue. Interesting phenomena also appear in non-equilibrium systems, such as the enhancement of diffusion during mixing due to the correlation of velocity and concentration flu...
متن کاملExplicit-Implicit Scheme for Relativistic Radiation Hydrodynamics
Relativistic flows appear in many high-energy astrophysical phenomena in which the magnetic field has a crucial role in dynamics. For example, magnetic fields connecting an accretion disk with a central star, or, different points of accretion disks are twisted and amplified due to the differential rotation, launching jets. Also magnetic fields play an important role in accretion disks to transp...
متن کاملComparison of Monte Carlo Methods for Nonlinear Radiation Transport
Five Monte Carlo methods for solving the nonlinear thermal radiation transport equations are compared. The methods include the well-known Implicit Monte Carlo method (IMC) developed by Fleck and Cummings, an alternative to IMC developed by Carter and Forest, an “exact” method recently developed by Ahrens and Larsen, and two methods recently proposed by Martin and Brown. The five Monte Carlo met...
