The aerodynamics in the oral-pharyngeal cavity is to be studied using the finite element method. The geometry of the oral-pharyngeal cavity is obtained from computer reconstructed CT scans of a human mouth and throat. A full 3D turbulent flow simulation is to be performed. The ultimate goals are to use a understanding of the aerodynamics in the mouth and throat to evaluate the deaggregation and deposition of aerosol particles inhaled into the mouth.

研究口咽腔的空气动力学 用有限元方法。 口咽部的几何形状 腔是从计算机重建的CT扫描的人， 嘴和喉咙。 一个完整的3D湍流模拟将是 执行。 最终目标是利用对 在口腔和喉咙的空气动力学，以评估解聚， 吸入口中的气溶胶颗粒的沉积。
