Numerical Simulation of the Two-Phase Flow in a New Type Cyclone
A new type cyclone with oblique top, transitional volute chamber, eccentric inner cylinders and sloping outlet were designed and manufactured by numerical analysis, which had been applied to the five-stage preheater in the cement plant with the capacity of 5000t/d. To simulate the gas flow field and particle trajectory in cyclone, the Fluent software was used, and the RNG k-ε model and discrete random walk model were proposed. The flow characteristics of gas-solid two-phase were analyzed. It is found that the strongly swirling flow occurs in the new type cyclone, and the particles of raw meal can be more efficiently separated from the gas.
