Abstract
Two-dimensional numerical simulations are used to explore the mechanism for asymmetric deflection of the glottal jet during phonation. The model employs the full Navier-Stokes equations for the flow but a simple laryngeal geometry and vocal-fold motion. The study focuses on the effect of Reynolds number and glottal opening angle with a particular emphasis on examining the importance of the so-called "Coanda effect" in jet deflection. The study indicates that the glottal opening angle has no substantial effect on glottal jet deflection. Deflection in the glottal jet is always preceded by large-scale asymmetry in the downstream portion of the glottal jet. A detailed analysis of the velocity and vorticity fields shows that these downstream asymmetric vortex structures induce a flow at the glottal exit which is the primary driver for glottal jet deflection.
摘要
采用二维数值模拟研究了发音过程中声门射流不对称偏折的机理。模型采用全纳维-斯托克斯方程描述流动，但喉腔几何形状和声带运动较为简单。研究重点关注雷诺数和声门开度的影响，特别关注所谓的“附壁效应”对射流偏折的重要性。研究表明，声门开度对声门射流偏折没有实质性影响。声门射流的偏折总是先于声门射流下游部分出现大尺度的非对称。对速度和涡量场的详细分析表明，这些下游非对称涡结构在声门出口处产生了流动，这是导致声门射流偏折的主要原因。
