couple output of transport of species physics to mixture model physics

Please login with a confirmed email address before reporting spam

HI,

I wanted to see if anyone can guide me on how to use the output from transport of diluted species as an input to the mixture model physics.

I have 3 species undergoing a simple chemical reaction A+B->C that is solved using the transport of diluted species. I get an output of product C. The units are in mass concentration (mol/m^3).

The mixture model laminar interface lets you define dispersed volume fraction. So I convert my mass concentration from the transport physics to volume concentration and I get a conversion constant.

Lets say, cC is mass concentration obtained from transport of diluted species
cS is the dispersed volume fraction in mixture interface

The relationship between them is cS=2.9*cC. I want to use that as input to my inlet node in the mixture interface. How do I couple them?

I am attaching the model and the excel sheet calculations as well a screenshot of the Species C output that I am trying to model in mixture interface.

Please help/guide.
