Turbulent Dispersion Force

    • Diogo Martinho

      Dear all, 

      When reading the Theory Guide, equation 18.312 and 18.313 define the Turbulent dispersion force according to Burns et al. 

      Do you know how can I change (if possible) the sigma_{pq}, which by default is 0.9?

      Thanks in advance.

      Hello, it seems like it can not be changed directly but it could be done using UDFs, not sure though. You can get the sample UDF code if you search it on the internet. Below is the link of a section of the Ansys Fluent User Guide where you can find the steps for setting Turbulent Dispersion Force using various models.
