| 中文摘要 | 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 ui'(t) are imposed on the particle's motion for n time steps determined by the calculation of the auto-correlation coefficient between ui'(t) and ui'(t-nt) 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. |
