Hi everyone, am new with openfoam and for my thesis i have to study a 3-phase fluid (oil+water+air) so i'm using multiphaseInterFoam, but i need to add temperature to my solver, so i follow the tutorial avaible for the icoFoam solver but now i need to add the multiphase effect to this ecuation.

i figure that it can be done treating DT (Thermal diffusivity) in the same way that rho but im not really sure how do i have to change the code or where is calculated the rho field as a mean weight by the volumes fraction.

if anyone could help me i will be really appreciate

Nicolas

Hello Nicolas,

Have you ever looked in the twoPhaseEulerFoam solver? It is for two phases, but it contains energy equations for both phases, heat exchange between them, etc... Perhaps it could inspire you?

Kind regards,
Ramon

hi RjwV thanks for your help, i was actually looking at compresiblemultiphaseinterfoam and it helps me a lot. Now i have another problem, how can i add a new propertie to each phase? i modified the phase.h and the phase.c to add a new propertie DT but i cant compile, here are my two files:

phase.h

Code:
#ifndef phase_H
#define phase_H

#include "volFields.H"
#include "dictionaryEntry.H"
#include "incompressible/viscosityModels/viscosityModel/viscosityModel.H"

hi kebsiali thx for your answer, yes am already see them and they didnt help me with my problem, speacialy because multiphaseinterfoam has many diferences with interfoam, specially in the library, i couldnt extend that example to multiphaseinterfoam.

have you read my last message? have any idea why its giving me that error when i try to compile te library?

Thanks for your time and help!

Thanks every one for your help, finally i could make it work, i found the error, forgot to put "," at the end of the rho_(phaseDict_.lookup("rho")) line.

Code:
    rho_(phaseDict_.lookup("rho")),
      
    /*##########################*/
    DT_(phaseDict_.lookup("DT"))
    /*##########################*/

{}

Hi nthiers,

I am also attempting to add temperature to multiphaseinterfoam. I have modified the phase.h and phase.c files as you suggested. I have also modified the multiphasemixture . and .c files. Is this necessary? I cant even get the solver to read in an extra transport property at this time. I am defining a volscalarfield kappasolid and using mixture.kappasolid() bu getting an "undefined reference" call. Did you just modify the phase files and if so how did you call your DT variable in your code if you dont mind me asking

Best regards,

Tom
