Abstract:
In this paper, a new numerical method, the coupling method of spherical
harmonic function spectral and streamline diffusion finite element for unsteady Boltzmann
equation in the neutron logging field, is discussed. The convergence and error estimations of this
scheme are proved. Its applications in the field of neutron logging show its effectiveness.
