🔥 Rijke Tube - 3D Blender Glass Pipe, Glowing Gauze and Oscilloscope

A thermoacoustic oscillator: a heated gauze in an open vertical tube feeds energy to the sound field only when heat release and pressure are in phase (Rayleigh criterion). Move the gauze, change the heat-release delay and watch growth rate, limit cycle and pitch.
