Okay. I did some reading on Helmholtz resonators and can see how these perforation holes may act with the volume of the muffler to be a resonator of such kind. However, I am not sure how to apply it with these boundary conditions...
The equations I found online for sizing the helmholtz...
Hello, I am a student designing a muffler system for a motorcycle engine used in a collegiate racing team. Our team doesn't have access to an industry standard engine simulation software, so determining some design parameters is coming down to making best guesses based on data found in reports...
