| Abstract: | In a circular bend which is vertically up to horizontal, a numerical simulation for the two phase flow and concentration field of coal pulverized and air showed that the concentration near the back line of the outside in bend is higher than the concentration of the inside obviously. It verified the principle of formation and separation of pulverized coal in different concentration in circulaz bend and gave a basis of theory for measures to improve effect on separation of pulverized coal in different concentration. |

| Keywords: | circular bend two phase flow of air and solid numerical simulation |
