Defined pressure drop between two fluid regions

dasith0001 · March 11, 2022, 00:12

Hi Formers,

I have this question for some time and I could not yet figure out a way to do it. Here is my question.

1. There is two fluid domains with same thermophysical properties. Each fluid domain can have a inlet and a outlet. (fluid domains should have at lease one external boundary)

2. Two domains are physically connected by a narrow channel.

3. I want to define a pressure gradient between the internal surfaces of the narrow channel. ( so that the narrow channel basically acts as a relief valve).

Could you suggest me an any direction setting up such a case? Or is it even possible to do this in OpenFoam

? Your help is greatly appreciated.

Thank you.
Dasith
