Fluid-Particle Interaction with Rotor/Stator interface

LDVVKI

Hello,

I am performing Fluid-Particle Interaction simulation with Rotor/Stator interface.

I have so far tried mixing plane and frozen rotor approach.

Both simulations run, however the results in CFView do not show quantity regarding Lagrangian particle tracking. (I can see the name of quantity but the values are all zero).

Is Fluid-Particle Interaction model compatible with Rotor/Stator interface?

Thank you in advance.

    Hello,

    You can find the limitations of the Fluid-Particle Interaction module here. See the page "Fluid-Particle Interaction". The following should be kept in mind:

    • The Lagrangian Module is compatible only with the mixing plane approach for Rotor/Stator interfaces.
    • The Lagrangian module in parallel mode is not compatible with NMB connections.


    Could you check the p0.log file in your computation directory for a section called "Particle tracking summary"? There should be some particle statistics in that section. Could you please paste it in your reply?

    Best regards,

    Botond

    Hello Botond,

    Thank you for your prompt response.

    Excuse me for lack of knowledge about limitation, as I was using FINE/OPEN9.2 and referring corresponding manual, I did not see the R/S interface is compatible only with mixing plane. Is the limitation of FINE/OPEN 11.1 same as the one of 9.2?

    Also when mixing plane approach is used, how the particle motion is treated when they face discontinuity of flow at mixing plane? 

    Somehow I can not find the log file, so I restarted the computation, I will paste it here as soon as it is ready.

    Best regards,

    Hello,

    You can find information on compatibility in the compatibility matrix of the documentation shipped with the version you are currently using. You can find the matrix under the "What's new" section of the 9.2 manual. The mixing plane-related limitation stated above is the same in versions 9.2 and 11.1

    Regarding the treatment of particles crossing an R/S interface, please see the this Theory Guide page. 

    Best regards,

    Botond
