Streaming-matrix hybrid method for discrete-ordinates calculations

Conference ·
OSTI ID:6615682
The streaming matrix hybrid method (SMHM) is a deterministic streaming method applied in void regions within a discrete-ordinates problem. The SMHM is used within the discrete-ordinates space-angle sweeping scheme so that it remains inside the standard discrete-ordinates inner iteration procedure. Streaming matrix equations are derived from the integral transport equation; a brief description of the implementation of the SMHM in discrete-ordinates transport codes is presented. The SMHM is applied to a cylindrical duct problem (L/D = 10) and compared with discrete-ordinates and Monte Carlo solutions. The SMHM provides more accurate results than discrete-ordinates without undue run-time or storage penalties.
