Flow separation on transversal ribs in an open channel

Original language description

Modelling of turbulent flow in an open channel with two transversal ribs 30x30mm on its bottom was carried out for various geometrical configurations. The analysis wac concentrated on development of flow separation behind ribs and on the corresponding changes of free surface. The pressure drag of individual ribs was investigated including their dependence on the rib spacing, as well as the origin of secondary flow near the side walls of the channel behind ribs. Numerical results obtained by the softwareANSYS CFX 11.0 were compared with experiments. carried out by means of LDA and PIV techniques in free-surface water channel 200x200 mm with one and/or two transversal ribs 10xl0 mm with various spacing.
