| Abstract: |
| In simulating gas-solid multiphase flows,traditional point-particle model will not be applicable when the scale of the solid is beyond the Kolmogorov scale,for the surface and the volume effect will significantly affect the fluid phase.With DNS(direct numerical simulation)-immersed boundary method,flows with different turbulent intensities past a stationary cube particle larger than the turbulent Kolmogorov scale are simulated.The boundary effect exerted by the particle on the turbulence and the forces endured by the particle are analysed. |
