finding resonant frequency of a pipe

Please login with a confirmed email address before reporting spam

I am a beginner to COMSOL. I would like to find acoustic frequency response of a pipe. I am thinking to use pressure acoustics physics and frequency study. Define an inlet port and outlet port on both ends. What would be the best approach for this project?

You should go for the simplest approach in the beginning, and preferably something that has an analytical solution in common textbooks. So for example a velocity condition in one end and hard wall at the other. Use Pressure Acoustics and Frequency study as you mention, and plot analytical and numerical solutions together to make sure that everything works.
