摘要

A time-series stochastic separated flow (TSSSF) model is proposed to obtain more reasonable statistical characteristics of two-phase turbulent flows. The sampled instantaneous fluctuating velocities of the gas phase u'_i(t) are imposed on the particle's motion for n time steps determined by the calculation of the auto-correlation coefficient between u'_i(t) and u'_i(t-nΔt) at each time step. An application of the model is performed in a turbulent two-phase flow over a backward facing step. The statistical particle phase velocities and particle concentration contours agree well with the experimental data and large-eddy simulation results, respectively. The present model can represent the unsteady flow mechanisms and therefore improves the prediction of particle dispersion.
