抄録

This paper is concerned with the numerical analysis of particulate jet generated by solid particles falling from a slit orifice into an unbounded quiescent air. A two-dimensional vortex method, proposed for the simulation of particle-laden free turbulent flow in prior papers, is employed for the analysis. The falling particles induce complicated air jet involving large-scale eddies around the jet. The air takes its maximum velocity at the center line of the jet. The particle velocity is higher than the free falling velocity of a single particle. The effects of the diameter and density of the particle on the velocity distributions of the air and particle are investigated. The entrained air flow rate is favorably compared with the value predicted by an analytical model.
