The paper deals with the issues of stochastic dispersion models for the inertial particle turbulent flow. Thereby, dispersion models are applied to generate the instantaneous velocity of the fluid at particle location to reproduce the effect of turbulence on particle transport within an Eulerian–Lagrangian approach. Especial focus is on the influence of unsteady calculation of carrier phase in combination with unsteady phase coupling. Computations are carried out in a particle-laden turbulent shear flow using three dispersion models. It turns out that accurate prediction of the carrier phase is essential to predict the dispersion in an acceptable level of accuracy.
