At normal temp and pressure, does fluent assume dissolved oxygen content in water to be 7 ppm?
or if not what is the correct value? and how to assign a new value? |

Use a Henry coefficient (for O2 this is about 45000 bar at 25oC). It relates the partial O2 pressure in the gas phase to the mole fraction in water: Pi = H*x.
Does this help? |
