Default Unsteady flow through 3D pipe
Posts: n/a
Dear All,

I am trying to simulate unsteady flow through a 3D pipe. I need to define step and impulse mass inflow excitation as the boundary condition at inlet.

Can anyone provide idea or literature on above inlet BC & how to define the same in Fluent?

Thanking you, Abhijit

you have kinds of acoustic problem

I mean your fluid is media for acoustics

first, you imposed period mass flow rate or pressure on inlet condition

second, setting pressure BC on outlet condition.

you need to consider a resonance by acoustic effect
