Abstract

The settling velocity of suspended particles in the ocean mixed layer was studied by analyzing the Lagrangian motion of a large number of particles in the three dimensional turbulent flow simulated by LES model. The presence of Langmuir circulation (LC) can suppress the particle settling in the ocean mixed layer. To stimulate LC, momentum equation was modified by including a vortex force and an additional advention by Stokes drift. The two different type of the ocean mixed layer i.e with and without LC were investigated along with three different types of particles.
