Abstract: The semicircular canals (SCC) are fluid-filled inner ear structures designed to detect circular or angular motion. In this study we modeled three-dimensional biomechanical model of SCC and compared results with real patient case for the Benign Paroxysmal Positional Vertigo (BPPV) disease. Model consists of full 3D fluid-structure interaction incorporating particles, wall, cupula deformation and endolymph fluid flow. A full Navier-Stokes equations and continuity equations are used for fluid domain with Arbitrary-Lagrangian Eulerian (ALE) formulation for mesh motion. For cupula deformation with fluid coupling, fluid-structure interaction is used. The numerical results are compared with real experiment for BPPV test and cupula deformation for head manoeuvre from 0 to 30°. The results could be used for better understanding of BPPV disease diagnosis.
