Hi all,
I have a batch microreactor with cubicle shape. Inside there is a liquid water which contains a specis A. A is getting converted into solid B. I am modeling this using multiphase eulerian model. Initially there was no phase B. As time progresses B is produced. Overall mass of system must remain conserved.
What I see is that overall mass of the system increases with time. How this is possible?
Can anyone please help me?
Thanks
Vivek
It's possible if the source term of B is not exactly equal to sink term of A, since A must decay to get B. This can be checked by plotting the concentration profile of both A & B with time where conc. of A should decline and conc. of B must rise.
Vivekananda, is there a third member to the reaction from A to B? It is possible that the intrinsic addition of this member is what is causing the mass balance error. What I mean is, if the reaction is of the form:
A + C ----> B
it could be possible that C is not explicit present in the domain, but is being modeled by a coefficient that is multiplied to A.
