Lewis' research includes combining finite element
with other methods for the solution of the Boltzmann
equation for radiation transport problems in six-dimensional
space-angle-energy phase space. Applications range
from radiative heat transfer to the simulation of
neutron transport in nuclear reactor cores. His
current investigations are focused on neutron transport
methods for treating the complex interactions between
fuel-coolant lattices structures and more global
effects in large power reactor cores. Under investigation
are hybrid finite element and finite subelement
formulations for treating spatial variables, tailored
spherical harmonic expansions in angle, space-angle-energy
adaptive grid algorithms, and response matrix solution
methods for parallel computers. |
