🔊 COMSOL Tutorial: Acoustic Radiation Impedance of a Tube (Part I) 🎧

In this video, I demonstrate how to calculate and plot the acoustic radiation impedance of a tube using COMSOL Multiphysics. The model is built using the Pressure Acoustics, Frequency Domain physics interface. I apply normal acceleration at the inlet and use impedance boundary conditions to evaluate the radiation characteristics.

🧠 What You’ll Learn:
✅ How to apply normal acceleration in COMSOL
✅ How to set up impedance boundary conditions
✅ How to compute acoustic radiation impedance
✅ Use of frequency domain study for acoustics
