内容記述 | The particulate jet generated by small solid particles falling from a round orifice into an unbounded quiescent air is simulated. The three-dimensional vertex method for gas-particle two-phase free turbulent flow proposed in a prior study is employed for the simulation. It is clarified that the falling particles induce complicated three-dimensional unsteady air jet involving large-scale eddies. The air takes its maximum velocity at the jet centerline,and the velocity profile satisfies the self-similarity around the centerline. The effect of the particle diameter on the velocity distribution for the two phases is investigated. The entrained air flow rate is favorably compared with the value predicted by the analytical models. This indicates the applicability of the present method for the particulate jet. | |||||
