Schlieren flow visualization experiments show that a stable vortex is developed downstream of the valve during the closingKeywords: Aerodynamics; Amplitude modulation; Engine cylinders; Flow patterns; Flow visualization; Mathematical models; Oscillations; Schlieren systems; Valves (mechanical); Vortex flow; Flow structures; Self-oscillating reed valves; Acoustic generators200110.1006/jsvi.2001.36772015-12-10
