| 摘 要： | Gas-solid two-phase turbulent plane jet is applied to many natural situations and in engineering systems.To predict the particle dispersion in the gas jet is of great importance in industrial applications and in the designing of engineering systems.A large eddy simulation of the two-phase plane jet eas conducted to in-vestigate the particle dispersion patterns.The particles with Stokes numbers equal to 0.0028,0.3,2.5,28(corresponding to particle diamster 1μm,10μm,30μm,100μm,respectively)in Re=11300 gas flow were strudied.The simulation results of gas phase motion agreed well with previous experimental results.And the simulation results of the solid particles motion showed that particles with different Stokes number have dif-ferent spatial dispersion;and that particles with intermediate Stokes number have the largest dispersion ratio.

| Abstract: | Gas-solid two-phase turbulent plane jet is applied to many natural situations and in engineering systems. To predict the particle dispersion in the gas jet is of great importance in industrial applications and in the designing of engineering systems. A large eddy simulation of the two-phase plane jet was conducted to investigate the particle dispersion patterns. The particles with Stokes numbers equal to 0.0028, 0.3, 2.5, 28 (corresponding to particle diameter 1 microm, 10 microm, 30 microm, 100 microm, respectively) in Re = 11 300 gas flow were studied. The simulation results of gas phase motion agreed well with previous experimental results. And the simulation results of the solid particles motion showed that particles with different Stokes number have different spatial dispersion; and that particles with intermediate Stokes number have the largest dispersion ratio. |
