volume fraction to concentration
Problem: passive scalar transported by background fluid with eulerian multiphase mixture model. How can I convert the transported phase, reported in Fluent as a volume fraction, to a concentration [kg/m3]? Should I multiply the transported scalar volume fraction by the scalar density?
Thanks in advance! Esther |
Re: volume fraction to concentration
yes, if you have your phase of interest with a volume-fraction Vi/V, you can find the mass of phase i in volume V (total volume of the mixture) as (Vi/V)*rho. So indeed you're right: just multiply. I'd suggest to do this in a user defined field function so that you can easily postprocess using this quantity.
good luck, Laika, still orbiting |
Re: volume fraction to concentration
Many thanks, Laika. I used a custom-field function to post process volume fraction as you suggested.
Very kind of you. Bye. Esther |
