Effectiveness of three rebalance methods in deep penetration problems. [LMFBR]

PDF Version Also Available for Download.

Description

The space-rebalance method brought important new capability to discrete-ordintes calculations by using an easily-solved procedure. Later, diffusion synthetic acceleration used the diffusion equation as the auxiliary equation. Application of this new approach has been slow, partially due to concomitant restrictions. Aull et al showed a reformulation which brought compatibility with weighted-difference and negative-fixup schemes. Miller showed that the differential forms of the conventionl space rebalance (CRB) pand the newer methods could be derived from a common framework. This paper will, similarly, cast the difference form of Aull's consistent diffusion acceleration (CDA) into the same form as CRB and will indicate ... continued below

Description

The space-rebalance method brought important new capability to discrete-ordintes calculations by using an easily-solved procedure. Later, diffusion synthetic acceleration used the diffusion equation as the auxiliary equation. Application of this new approach has been slow, partially due to concomitant restrictions. Aull et al showed a reformulation which brought compatibility with weighted-difference and negative-fixup schemes. Miller showed that the differential forms of the conventionl space rebalance (CRB) pand the newer methods could be derived from a common framework. This paper will, similarly, cast the difference form of Aull's consistent diffusion acceleration (CDA) into the same form as CRB and will indicate a third approach suggested by this comparison. Variations of these methods will be tested on deep-penetration problems.
