Several problems with modeling liquid-gas transfer reactor

[james jery]

Hi!
I want to model a gas-liquid packed bed reactor with Cantera. The modeling process primarily involves gas-liquid mass transfer terms, and I meet serval problems:

1.
The mass transfer coefficient changes with the state of the reactor, I attempted to simulate gas-liquid mass transfer by modifying the chemical mechanism file with the reaction SO2(g) <=> SO2(aq) through the chemical reaction module, as shown in the code. Is this approach feasible?

2.
When the gas-phase reactor energy is set to "on," the gas temperature drops drastically. When the liquid-phase reaction energy is set to "on," an error is reported. How does it happen?

3.
I want to use Cantera as a chemical source term. How can I obtain its source term and implicit source term? I've tried in my giving code, am I right?

Thank you.
