NUMERICAL STUDY ON BOUNDARY LAYER FLOWS UNDER SOLITARY WAVE

摘要：

Ocean waves near breaking in the surf zone often have narrow crests without trough resembling solitary waves. The transition to turbulence prediction together with an understanding of the immediate stages of turbulence development, are of fundamental importance for the accurate prediction of the initiation of sediment motions. The baseline (BSL) k- ω turbulence model is applied to predict and investigate the laminar, transitional and turbulent flow characteristics under solitary waves. Model is validated by the linearized boundary layer equations of motion velocity profile in the laminar boundary layer under solitary wave. Moreover,hydrodynamic conditions were observed subsequently and interpreted using two methods,namely turbulent kinetic energy and bottom shear stress methods.
