How to input different thermal conductivity for the wall and particles and solve conjugate heat transfer

I am performing heat transfer simulation for pure granular flow in MFIX DEM.

I want to introduce constant temperature at front and rear wall, adiabatic wall for the right and left wall.

I don’t want to set any temperature for the fin wall. Since the heat should get conducted (diffused) by fin wall from the front and rear wall. This is occur due to conjugate heat transfer. I don’t know whether Mfix has the capability to do this.

  1. Can you please help me out in setting up conjugate heat transfer?
  2. Also the wall material is different from particle material. How to set up different thermal properties for the wall?

Thanks @jeff.dietiker

MFiX does not have the capability to do conjugate heat transfer.

Thanks for the response.

Also, can you please tell me whether setting actual youngs modulus and poissons ratio are necessary for conduction or is it optional? I have already reduced the youngs modulus in Hertz collision model.

         IF(E_YOUNG_ACTUAL(M) == UNDEFINED) THEN
            MSG=''; WRITE(MSG,"('Phase ',I2,' Actual EYoungs')") M
            WRITE(ERR_MSG,2002) 'E_YOUNG_ACTUAL', MSG
            DO_AREA_CORRECTION = .FALSE.
            CALL LOG_WARNING()
         ENDIF

These settings are optional, if they are omitted the area correction will be disabled and you will get a warning message.

Also, please create a new topic for questions instead of adding to a thread which has already been marked ‘solved’. This makes it easier for us to keep track of which questions are answered already, and makes it easier for other users to search the forum.
