I want to simulate a particle surface reaction, but the result is not completely convergent. When gas comes into contact with particles, CO2 suddenly increases by 10-100 times, which seems to contradict the law of conservation of mass.  In addition, the more CO2 there is in an area, the less N2 there is. Increasing the number of grids and shortening the time step is still the result. Did I make a mistake in setting it up? Or is Fluent unable to simulate this catalytic reaction? I consulted the ANSYA theoretical manual, which provides an introduction to this reaction. These are some of my pictures. ( time step is 0.0001s)<\/p>\n

Thank you for any help.<\/p>\n
