使用“SedWaveFoam” -- 三维两相流求解器，对沙洲上的速度和加速度偏斜近破碎波驱动的薄板流的数值研究

• 针对沙洲上近破波驱动的薄板流，验证了自由表面解析的欧拉两相流模型。

• 由于速度波和加速度斜波的渐进波流效应，陆上定向沉积物通量得以提高。

• 对于由于瞬时床层破坏而引起的加速倾斜的波浪，陆上运输的增强更为重要。

   

  A numerical study of sheet flow driven by velocity and acceleration skewed near-breaking waves on a sandbar using SedWaveFoam

   

• A free surface resolving Eulerian two-phase flow model is validated for sheet flow driven by near-breaking waves on a sandbar.

• Onshore-directed sediment flux is enhanced due to progressive wave streaming effect for both velocity and acceleration skewed waves.

• The enhancement of onshore transport is more significant for acceleration-skewed waves due to momentary bed failure.
