ABAQUS-FLUENT Coupling for Larynx Models

Used Approach (Software, Numerics, Modelling)

Studies of fluid structure interaction are conducted for three dimensional larynx models. Simulations were performed using the codes FLUENT and ABAQUS coupled by the code MpCCI.

Expected Results

Phonation is defined as the use of the laryngeal system to generate an audible source of acoustic energy. The main vibratory components of the laryngeal system are the vocal folds. Vibration of vocal folds is induced by air flow. We study the characteristics of vocal fold self oscillation as a process dependent on several energy dissipative mechanisms, including dissipation in the fluid, due to turbulence, and in the tissue, due to visco-hyperelasticity.
