This paper investigates the nonlinear characteristics of the mouthpiece-reed system of a clarinet using the lattice Boltzmann method (LBM) in a two dimensional domain. The mouthpiece has been investigated for cases of both a fixed reed and a moving reed, with the outlet of the mouthpiece being replaced by an absorbing boundary to thwart possible acoustic oscillations. The influence of the geometry of reed channel has been investigated. Numerical results are compared to the quasi-stationary model based on a simplified memoryless reed and the Bernoulli flow.
