Modelling Wave and Fluid Propagation in Wind Instruments - Methods and Applications
Wilfried Kausel, Helmut Kühnelt · 2003
Current approaches to model wave propagation and fluid-acoustics in one-, two-, and threedimensional acoustical systems are covered and present ways to model sound production mechanisms in instruments are outlined. Emphasis has been put on the recently developed concept of the Lattice Boltzmann method in the context of flow-acoustics. It allows the study of the interaction between the jet and the acoustic field in flute-type instruments. Another branch of research is a time-domain simulation of trumpet sound generation including wave propagation on the lip surface.
