抄録
A large eddy simulation (LES) of the tidally induced bottom boundary layer process in the coastal ocean is carried out and the obtained results are used to examine the suspended particulate matter dynamics. Special attention is directed to the dependence of the vertical diffusive process of the particles on their size and density. We find that, presumably because the time scales of the particle response to water motions are much less than those of interest in this study, the magnitudes of the vertical velocities of particles are almost identical to those of seawater and fairly independent of their size and density. It is suggested that the vertical diffusivity coefficient of particles is of the same order as the vertical eddy viscosity or diffusivity coefficients derived from the velocity or temperature fields of seawater.
