NUMERICAL PREDICTION OF SEDIMENT TRANSPORTATION IN A BRANCHED NON-UNIFORM DUCT

The transportation of sedimentation in 2D branched and non-uniform duct flows is numerically predicted with a computational method, which has a conservative scheme for convection terms in 5th-order accuracy with a flux control technique (FVM-QSI scheme). The governing equations including a turbulenc...

Zusammenfassung:The transportation of sedimentation in 2D branched and non-uniform duct flows is numerically predicted with a computational method, which has a conservative scheme for convection terms in 5th-order accuracy with a flux control technique (FVM-QSI scheme). The governing equations including a turbulence model are discretized with strong conservative forms in curvilinear coordinates on the collocated grid system. The predicted results are compared with the measured values and its applicability is discussed.
