Abstrakt: The translational and orientational dynamics of non-spherical particles in a turbulent channel flow at shear Reynolds number Reτ=300 is studied using an Eulerian-Lagrangian method coupled to an Eulerian rotational equation. Results show that particle dispersion to and away from the wall differs with shape, while the particle orientation exhibits several distinctive states depending on the particle shape andinitial position and orientation. There is a transition from one state to another with simulation time. [ABSTRACT FROM AUTHOR]
