Using the OpenFOAM open source software, a numerical study of the turbulent flow over a wavy surface was carried out for various values of the amplitude and wavelength of the disturbance of the channel wall. The RANS and LES models were used to describe the turbulent characteristics. The Reynolds number in the flow was 20000. Average profiles of velocities and shear stresses on the channel wall were obtained. The values of the amplitude and phase shift for disturbance of the shear stress were calculated for various geometrical parameters of the channel. The comparison was made with the theoretical model and experimental results.
Keywords: numerical simulation, RANS and LES models, wavy wall, shear stresses.
