Abstract

Turbulence fields are predicted with the aid of a ( K-ϵ) model supplemented with algebraic relations deduced from a second-order closure scheme. Then, the dispersion of discrete particles transported by the turbulence fields predicted above is computed. Modelling of the discrete particle dispersion is based on an Eulerian approach. The (monodispersed) particles are considered as a continuous field for which a transport equation is written. The transport equation contains a dispersion tensor which is computed in the framework of the (slightly extended) Tchen theory, assuming a two-parameter family of Lagrangian correlation functions for the fluid particles. Modifications can be included to account for crossing-trajectory effects. Predictions are compared with experiments from Snyder & Lumley (1971), Wells (1982, 1984) and Arnason (1982).
