Numerical Simulation Study on Airflow Structural Characteristics and Vortex Evolution in Human Mouth-Throat Model


Article Preview

Large eddy simulation was used to simulate the airflow movement and vortex evolution in human mouth-throat model in the conditions of the low intensive respiratory patterns, and the airflow structural characteristic and vortex evolution in mouth-throat model was discussed. The results show that two velocity growth points generated in pharyngeal and laryngeal region; the airflow separates in region near the pharynx and the separation zone appears near the anterior wall of pharynx; A turbulence jet appears in the glottal region and the airflow; the jets formatting in pharynx and laryngeal lead to two vorticity growth regions; flat vortex appeared in the throat; a curved vortex like the trachea wall appeared in the anterior wall of trachea, and nearly symmetric reverse vortex pairs appeared in the trachea.
