title = "Numerical investigation of shear stress under plunging breaker on a sloping beach",

abstract = "In this study, a two-dimensional numerical model (NEWFLUME) is applied to investigate the shear stress distributions in the bubbly flow on a sloping beach (1/20) under breaking waves. The numerical model solves the Reynolds equations for mixture flow and employs the volume-of-fluid (VOF) method to track the free surfaces. Turbulence closure is accomplished by the k-e scheme. An improved air entrainment model is incorporated to consider the effect of bubbles on the mean flow in present model. The bed stress distributions and the effect of bubbles on shear stress are investigated. It is found that the bed stress decreases by the existence of bubbles in the aeration region. The maximum value of time dependent total shear stress is damped approximately 12% and the depth integrated total shear stress shows a 20% decrement.",
