The Non-Classical Boltzmann Equation, and Diffusion-Based Approximations to the Boltzmann Equation
Martin Frank, Kai Krycki, Edward W. Larsen +1
We show that several diffusion-based approximations (classical diffusion or SP1, SP2, SP3) to the linear Boltzmann equation can (for an infinite, homogeneous medium) be represented…
Non-classical transport with angular-dependent path-length distributions. 2: Application to pebble bed reactor cores
Richard Vasques, Edward W. Larsen
We describe an analysis of neutron transport in the interior of model pebble bed reactor (PBR) cores, considering both crystal and random pebble arrangements. Monte Carlo codes wer…
Non-classical transport with angular-dependent path-length distributions. 1: Theory
Richard Vasques, Edward W. Larsen
This paper extends a recently introduced theory describing particle transport for random statistically homogeneous systems in which the distribution function p(s) for chord lengths…
Asymptotic Derivation and Numerical Investigation of Time-Dependent Simplified Pn Equations
E. Olbrant, E. W. Larsen, M. Frank +1
The steady-state simplified Pn (SPn) approximations to the linear Boltzmann equation have been proven to be asymptotically higher-order corrections to the diffusion equation in cer…
