| Abstract: | FLUENT was applied to simulate the two-phase flow field of gas-solid in stabilization and contraction stages of the sand/dust tunnel.Both the turbulence model for computation and the technology of dividing grid were presented.The distribution of the velocity gradient of the two phase flow-field in the stabilization and contraction was analyzed.The result showed that the reverse sandblasting is better than the positive. |
