Simulation of fluid flow and basilar-membrane motion in a two-dimensional box model of the cochlea

Abstract

We simulate the perilymph flow in the cochlea and the motion of the basilar membrane numerically. The full Navier-Stokes equations are solved. The basilar membrane is included in an approach similar to the immersed boundary method. A modelling concept to include the active amplification of the basilar membrane motion is proposed. All simulations are carried out in a two-dimensional box model with a solver optimized for high-performance computing. © 2011 American Institute of Physics.
