Abstract
In this work we investigate the validity of the following assumptions that were used in previous studies of the endolymph motion within the semicircular canals of the inner ear: (a) quasi-steadiness and therefore exclusion of the time derivative, (b) absence of advection, (c) insignicance of Coriolis and centrifugal forces. A parameter study is performed using the C++ based OpenFOAM® software library for nu- merical simulations on a nite volume grid. For validation purposes, the solutions are compared with results from the method of fundamental solutions to compute the ow in a quasi-steady Stokes flow regime. We conclude that the assumptions are valid for a standard head maneuver. Show more
