      In Fluent help, the equivalent particle scattering factor is defined in this way.

      we have emissivity, absorptivity, and scattering. 

      I don't understand the difference between the equivalent particle scattering factor and scattering factor f_pn. why  using (1-f_pn)?

      Another question is how it is associated with the volume.

      I suspect it'll be a maths definition somewhere, and may be defined in more detail in a reference given at the top of the section   https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v222/en/flu_th/flu_th_sec_mod_p1.html%23flu_th_radiation_p1_particles  

      The heat sink (source) to the fluid volume is given at the end of the above.

      Thank you Rob. I will check the documentary again.
