Abstract:

Based on the application software FLUENT in Computational Fluid Dynamics (CFD) and by using Eulerian multiphase flow，we carried out a simulation for heat transfer between coke particles and circulating gas with a 140t/h CDQ system of a coking plant to demonstrate the feasibility of this method and verify the correctness of the calculation results.Through the analysis of the results from several CDQ calculating conditions，we can also show the capability of multiphase flow model to describe the temperature variation of different grain\|sized coke.
