In this paper both Eulerian and Lagrangian approaches are used on the numericalcomputations of dilute gas-solid two-phase flows. In Eulerian approach the gas flow field in atwo-dimensional tunnel is computed by a general-used software. From this result the particletrajectory is computed by the model of one-way coupling using the knocking relation obtainedfrom the experiments. The computed result shows good agreement with that produced fromexperimental measurement. In addition, in order to consider the coupling effect between thetwo-phase, a two-way coupling model is also used to compute the particle trajectory, andproduced some useful conclusion. The presented computing program can be used to predictthe trajectory of solid particle in dilute two-phase flow.
