Description

This evidence describes the results of flow behaviors in gas-solid fluidized bed reactors with inclined slotted distributors. In Part A, the source terms of polymerization kinetics are given in Tables 1-3. The experimental setup is shown in Part B. In Part C, the videos showing the flow behaviors using different types of distributors including slotted distributor with inclination angle of 30 degrees, slotted distributor with inclination angle of 45 degrees, slotted distributor with inclination angle of 60 degrees and perforated plate distributor are given. For the slotted distributors, the tangential motions of particles are observed above the distributors due to high value of tangential velocity component. As the angles of the inclined slots increase, the bed height increases due to higher value of vertical velocity component. In the case of the perforated plate distributor, only vertical velocity component exists so the largest bed height is obtained.

Steps to reproduce

The multiphase flow behavior is studied in the experimental setup and the inclined slotted distributors are designed to improve the reactor performance. The Eulerian-Eulerian multiphase approach coupled with comprehensive kinetics and population balance model is developed in order to study the hydrodynamics, kinetics of reactions and particle size distributions in the gas-solid fluidized bed reactors. The predicted product properties agree well with the literature and industrial data. The developed approach enables the predictions of the hydrodynamics, kinetics of reactions and particle size distributions in the gas-solid fluidized bed reactors.
