A rigorous model for the simulation of chemical reaction in gas-particle bubbling fluidized bed: II. Application to gas combustion case
Simulation of gas combustion process in bubbling fluidized beds (BFB) using the model proposed in Part I is carried out. The predictions are compared against the experimental measurements and good agreement is observed. It demonstrates that the turbulent Schmidt number is changing throughout the BFB. Therefore, the conventional way of using constant turbulent Schmidt number for the simulation of BFB is questionable. (C) 2018 Elsevier B.V. All rights reserved.
