Thermoacoustic Oscillations in Supercritical Fluid Flows
… heated by blowing 800-950F nitrogen over them. Acoustic-mode oscillations, typically ranging from 100-500 Hz, occurred only when a large temperature gradient was created inside the heated fuel tubes. Pressure oscillation amplitudes ranged from 0.1-1.0 psi. Oscillations at the inlet and outlet …
