4. RESULT
Fig. 6 FSI model of semicircular canal and otolith
Fig. 7 presents the results when parallel movement condition is applied and the gravity
coincides. The movement of cupula is consistent with physiological sense.
Fig. 7 Pressure distribution by parallel movement in gravity condition
Fig. 8 shows that changing pressure of the fluid while otolith is falling and affecting all
area. Also Fig. 9 shows the displacement of cupula by changing pressure. The presence
of otolith affects the pressure of endolymph. High pressure acts on the bottom near the
cupula. The displacement of the cupula is large in the upper portion where relatively
low pressure is applied.
