On the physical origin of enhanced turbulent-dispersion of inertial particles in boundary layer flows

  title={On the physical origin of enhanced turbulent-dispersion of inertial particles in boundary layer flows},
  author={Julien Chauchat and David Hurther and Thibaud Revil-Baudard and Zhen Cheng and Tian‐Jian Hsu},
One of the most enigmatic science question concerning inertial particle transport by a turbulent boundary layer flow is the value of the turbulent Schmidt number as the ratio of particle diffusivity and turbulent eddy viscosity. Using direct acoustic measurement of turbulent particle flux profile, and two-phase flow turbulence-resolving numerical simulation, it is demonstrated that turbulent dispersion of particles is reduced rather than enhanced when predicted with existing literature model…

Turbulent Effects on the Settling Velocity of Suspended Sediment

The mean settling velocities of suspended sediments in turbulence have been examined. The settling velocities in a flume are directly measured by using an acoustic Doppler velocimeter. The results
