Model scope & assumptions

Resonant frequency follows f = sqrt(γ R T)/(2 L) for the first closed–closed longitudinal acoustic mode. Acoustic pressure and particle velocity use standing-wave mode shapes. Heat input and loss evolve a one-node thermal capacitance. A nonlinear envelope models onset and saturation, with empirical thresholds and stack coupling.

This is a physically informed educational model, not a CFD, Rott-equation, stability-design, combustion or certified thermoacoustic engineering solver. Acoustic wave fields are displayed in stroboscopic slow motion; numerical readouts update at the actual model frequency and time. No real hardware control is present.
