An improved spectral approach for solving the nonclassical neutron particle transport equation
L. R. C. Moraes, J. K. Patel, R. C. Barros +1
An improvement modification of the Spectral Approach (SA) used for approximating the nonclassical neutral particle transport equation is described in this work. The main focus of t…
On the calculation of neutron sources generating steady prescribed power distributions in subcritical systems using multigroup X,Y-geometry discrete ordinates models
Leonardo, R. C. Moraes, Hermes Alves Filho +1
In this paper a methodology is described to estimate multigroup neutron source distributions which must be added into a subcritical system to drive it to a steady state prescribed…
Transport Synthetic Acceleration for the Solution of the One-Speed Nonclassical Spectral S Equations in Slab Geometry
Japan K. Patel, Leonardo R. C. Moraes, Richard Vasques +1
The nonclassical transport equation models particle transport processes in which the particle flux does not decrease as an exponential function of the particle's free-path. Recentl…
Effect of variation in density on the stability of bilinear shear currents with a free surface
Ricardo Barros, José Felipe Voloch
We perform the stability analysis for a free surface fluid current modeled as two finite layers of constant vorticity, under the action of gravity and absence of surface tension. I…
A Spectral Approach for Solving the Nonclassical Transport Equation
R. Vasques, L. R. C. Moraes, R. C. Barros +1
This paper introduces a mathematical approach that allows one to numerically solve the nonclassical transport equation in a deterministic fashion using classical numerical procedur…
