  Hi all,
  I am simulating a pulsative flow in the suppressor (attached photos )
  Inlet B.C is pulsative mass flow rate, for outlet B.C I used ambient pressure for outlet B.C but the results weren't reasonable. The inner diameter is 20 mm, and the fluid is hydraulic oil with an 850 density and 0.039 viscosity. Also, the chamber diameter is 50 mm.
  I am wondering if I can use constant pressure in the outlet B.C while using a pulsative flow inlet?

  What do you mean by the results were not resonable? Can you provide more details?
