Extremium variational principles for the monoenergetic transport equation with arbitrary adjoint source (LWBR Development Program)

Technical Report ·
OSTI ID:6730860
A variational method is given for determining the lower and upper bounds for the monoenergetic transport equation with arbitrary adjoint source. The functional is chosen as a form of the one-velocity Boltzmann transport equation; spherical harmonics expansions are used as trial functions. Three types of boundary conditions (b.c.) are considered: vacuum b.c., symmetric b.c., and antisymmetric b.c. Mathematical properties of the functional are deduced; stationarity criteria are applied to the functional for all three types of boundary conditions. Lower and upper bounds are obtained for the functional. A numerical example is included. 18 references. (NSA 23: 23999)
