im trying to model a sound absorber duct and i have a problem with the absorption coefficient. i used the absorptive muffler tutorial to build my 2d model.
for the sound power P i have p^2/(rho*c)*S. im not sure of my integration, i tried to solve it this way intop2(abs(p)^2/(acpr.rho*acpr*c)*pi/4*d0) for the outlet and analog with p0 for the inlet.
but my results dont look like these from the tutorial. i also tried different variables and even a 3d model with the same setting like the tutorial and i still got different results..
did someone tried something similar and cane help me?
