Pressure definitions in Fluent

    • mh94

      Hi guys, 

      can someone tell me briefly how the following pressures are defined and/or calculated in Fluent?

      • absolute pressure

      • operating pressure

      • gauge pressure

      • total pressure

      • static pressure

      • dynamic pressure

      I've read up on them in the user's guide. However, with sentences such as "this pressure is this pressure relative to this pressure" and the lack of mathematical formulations, it's hard for me to understand the big picture.

      I've also checked the contour diagrams for each pressure and can ony came up with assumptions.

      Looking to forward to your reply! Thanks!
