the site suggested I should send you a pm. Hope it’s fine with you.
Why did you say the code it wrong? Do you have any comment looking at it?
It is a simple annular flow with harmonic compressible boundary conditions (a fundamental Hydraulic Damper).
yeah. rad is a scalar, so you aren’t integrating the thing you meant to.
yeah but velocity is a vector. its like doing a r1u1+r2u2…to get the volume flow rate.
but rad is a scalar, so it’s radu1+radu2…
rad is a vector, I have defined it above as range(0.01,0.017,length=N) from r1 to r1+delta with 101 point divisions making it 100 numerical spaces.
sorry, I missed that.
