jakatch Posted August 18, 2021 Share Posted August 18, 2021 Hi GWB team, I'm running a flow-through reaction with water permeating a parcel of rock. The incoming fluid is in equilibrium with CO2 in the atmosphere (pCO2 = 300 uatmos), but I do not fix CO2 fugacity. Question 1) If CO2 fugacity is not fixed, does that mean that there is no "head space" in the reactor to exchange with the fluid as it moves through the rock parcel? If CO2 fugacity is fixed, does that mean air-fluid exchange is happening? Question 2) I was wondering how is air-fluid gas exchange dealt with in GWB? What is the gas transfer velocity set as? Are there ways to edit this? Question 3) When reactant particles dissolve or precipitate, how does GWB deal with how particle size changes? Does GWB use a shrinking core model? Are there ways to edit this? Thanks for the help! Jo Quote Link to comment Share on other sites More sharing options...
