Ansys Fluent melting/solidification model equations

      Hi, 

      I have a few questions regarding the fundamental equations used in the melting/solidification model for phase change materials in ANSYS Fluent. 
       
      With reference to the energy and momentum sink equations (17.4-5) and (17.5-1) in release 12.0 of the Ansys Fluent theory guide, how is the fluid velocity term calculated, and where is the value of the mushy zone derived from?  I have attached the equations below for reference, and the theory guide can be accesed here. Thanks.
       
      Energy Equation:
       
      Momentum sink equation:

       
      Kind regards,
      Jada

      The velocity is fixed using that source term into the momentum equation. I recommend using supported Online Help. Release 12 is not supported anymore.

      Thank you for getting back to me.

      How are the velocity terms in the source term and energy equation coupled? Also, where can I locate the theory guide/supported help for the most latest release?

      Kind regards,

      Jada

      Check the Solidification and Melting Model in the Theory Guide: you won't miss it.

      To get the (online) help: wherevever you are in Ansys Fluent just Hit F1 then navigate to main Help landing page.
