The Project

In classical theory of linear neutral particle transport, the probability that a particle at a given point in space and traveling with known kinetic energy will experience an interaction is independent of the direction of motion and the path length, which is the distance traveled by the particle since its previous interaction (birth or scattering). In this situation the classical linear Boltzmann equation is used to model neutral particle transport problems, wherein the locations of the scattering centers are uncorrelated. In this project we propose to use the non-classical generalized linear Boltzmann equation as the mathematical model of neutral particle transport for random statistically homogeneous systems where in the distribution function for chord lengths between scattering centers is not exponential. This situation occurs in the description of photon transport in atmospheric clouds and of neutron transport in pebble-bed nuclear reactors.
