| Abstract: | In order to improve the separation mechanism, LDV (Laser Doppler Velocimetry) was used to measure the characteristics of gas turbulence flow in the cyclone tube. The distribution of mean velocity, turbulence density, power spectrum and vortex microscale were presented, and the effect of gas turbulence on particle separation was analyzed. Some conclusions were drown: there were different sizes of vortex in the cyclone tube; in the inner vortex region the vortex microscal was small, and the energy dispersion rate was high. |
