Abstract :
Flow behavior of the gas and particle in the pre-calciner was simulated through using the large eddy simulations and the kinetic theory of granular flow. The results of numerical calculation show the disciplines and features of the gases movement and the particles concentration distribution in the pre-calciner. This verifies that the design of the spouted pre-calciner is reasonable, and providing a theory basis for the further research about the heat transfer, mass transfer and chemical reaction process.
