Simulation of chemical reactions in a fluidized bed indicates Dt < Dt_min.With the developer’s help, the issue was resolved. However, I noticed that the fluidization state of the particles after incorporating the chemical reaction differs from that in the cold model.Below is the fluidization state of the cold model, which exhibits a bubbling bed configuration.
However, when I enabled the chemical reaction, the fluidization state appeared as follows:
Clearly, this is not a normal particle fluidization state; eventually, the particles will accumulate on both sides, and the gas will pass through the center, forming a channel.Here is my simulation file. Thank you!
