抄録
The three-dimensional lattice Boltzmann method (LBM) is used to simulate the behavior of bed-load layer in open channel shear flow. The 3D LBM for particle-fluid suspensions originally developed by Ladd (1994) has been extended to free-surface flow and to higher Reynolds number regime. The SGS turbulence term based on Smagorinsky model is also included in the LBM flow simulation. The present simulation predicts well the behavior of each particle in the bed-load layer both in saltation and sheetflow regimes. Results of the present simulation for the height and length of saltation,the bed-load velocity and the existing probability density agree fairly well with the experimental data from Gotoh et al. (1994).
