I was wondering if anyone has any experience with trying to calculate the acoustic perturbation pressure of a simple stationary cylinder in laminar flow. Specifically, I am trying to use the -dp/dt (time derivative of pressure) from a DNS (direct numerical simulation) of the flow solution for the laminar flow of the cylinder (Re=200). This term seems quite large up to 200+ in magnitude which perplexes me. I am trying to insert -dp/dt as a source in the pressure/energy equation. If anyone has any tips or thoughts please let me know. Thank you all so much. *YiLin Liu * *403-397-3457* *liuyilin.liu@gmail.com <liuyilin.liu@gmail.com>* MASc Student at CML <https://cml.mech.ubc.ca/> UBC
