Hello I'm using COMSOL 6.1 Reaction engineering module. I'm modeling a reaction in the form of :
A-->B+C+D+... the reaction describes the thermal decomposition of a solid material. I got the values of the reaction kinetics [ A, E] from TGA experiments. when I use the values to define the reaction constant [k] the reaction doesn't occur . I get a graph with the concentration of [A] as a fixed straight line and all products are at zero. has any one modeled reactions using kinetic values of TGA data before?! pls help
- I also want my reaction rate to be temperature dependent. my temperature is rising from 0K to 800K and then stays at that point. I tried to identify temperature as a function but I couldn't include the function in the rate constant. COMSOL wont recognize it. If anyone has such success modeling these type of scenarios. I would be grateful to hear you thoughts.
Best Regards
Simulating a chemical reaction in COMSOL Multiphysics involves using the Reaction Engineering interface. This interface allows you to set up and solve reaction systems involving multiple species and reactions. Here's a general guide on how to simulate a chemical reaction in COMSOL: The temperature influences the rate of a reaction. As the temperature increases, the rate of a reaction increases.
