Hello, community, I am looking for some advice and tips on how to implement chemical speciation in COMSOL. The objective is to couple mass transport processes, to calculate the pH along a distance.
Hello Matt Jackson and thank you for your interest in my question, I am looking something more like implementing chemical speciation coupled to transport equations in time dependent one dimension. A problem of transport and equilibrium reactions coupled
Help me out a bit. What do you mean by chemical speciation and transport? More details the better.
dear Matt Jackson
What I mean for chemical speciation is that: by a giving initial pH calculate the distribution of chemical species, components and complexes and how those species concentrations change as we change the pH of the solution. another way to see this is by solving the derivative: d(Cj)/d(pH) in which Cj is the concentration of one of many complex and how its concentration changes as we change the value of the pH in the bulk.
Dilute species transport (and chemical reactions module if needed) should be pretty straight forward. Look at example files.
