In FLUENT, when we do an open-ended domain natural convection problem, is the "guage total pressure" in the Pressure-Inlet boundary condition equivalent to the Stagnation Pressure at the inlet?

Hi Ravi,

When you model an open-ended natural convection problem and the flow is incompressible then the total gauge pressure at the panel of the Pressure Inlet is zero. The latter means that the static pressure difference (difference between the static pressure at the inlet region and the static pressure in a point outside the inlet at the same height where the fluid is motionless )is equal to the dynamic pressure.

I hope to help you!

i think it doesnot matter, if it is a incompressible flow, then the absolute pressure is meaningless, we only care about the relative pressure.
