Abstract EN
This study presents the results obtained from the numerical simulation on turbulent flows around a single groin for different orientations.
Here iRIC Nays2DH, which is based on 2D model, is used to simulate the flows in a straight open channel with groin of 45°, 90°, and 135° angled with the approaching flow.
A depth-averaged k-ε model is used as turbulence closure model with finite differential advections as upwind scheme.
The numerical results of velocity and bed shear stress profiles are compared with the available experimental data.
Good agreements are found between experimental and calculated results.
From the simulation, it is observed that the peak of velocity and bed shear stress is maximum at the position of head of groin when lateral distance y/l=1, where l is the groin length.
The position of maximum velocity and bed shear stress is found to be shifted towards downstream with increasing y/l.
The maximum velocity and bed shear stress for 135° groin are found lower than the other two cases for all the sections of y/l.
