Computational analysis of the dynamic flow in single-reed woodwind instruments

The dynamics of the air flow within the mouthpiece of single-reed wind instruments plays an important contribution to the acoustic behavior of this type of systems, particularly during transient regimes. In this work, a two-dimensional numerical model of the mouthpiece-reed system is used to evaluate the behavior of the flow within the mouthpiece at two different frequencies within the playing range of the clarinet. The relationship between volume flow and blowing pressure, as well as the behavior of the vena contracta along one duty cycle are compared with the available analytical models and with recent experimental observations.
