The functions of the nasal cavity are closely related to its structure. In this study the three-dimensional finite element models were established based on the clinical data of twenty-four volunteers to study the influence of nasal structure on nasal functions of heating the inhaled airflow. Numerical simulations mainly concerning the airflow distribution and the airflow temperature are performed. The character of airflow heating process in these models is gained from the simulation results of these nasal cavities. The parameters describing the geometry of nasal cavity, such as the surface area of nasal airway and the volume of nasal cavity, are considered to be related to the nasal function of heating the inhaled airflow. The approximate function describing the relationship between the geometric parameters of the nasal airway and the nasal functions is gotten. This study can provide a numerical platform for studying some clinical problems and will contribute to the further research on the relationship between nasal structure and nasal functions.
鼻腔的功能与其结构密切相关。在本研究中，基于24名志愿者的临床数据建立了三维有限元模型，以研究鼻腔结构对加热吸入气流的鼻腔功能的影响。进行了主要涉及气流分布和气流温度的数值模拟。从这些鼻腔的模拟结果中获得了这些模型中气流加热过程的特征。描述鼻腔几何形状的参数，如鼻气道表面积和鼻腔容积，被认为与加热吸入气流的鼻腔功能有关。得到了描述鼻气道几何参数与鼻腔功能之间关系的近似函数。本研究可为研究一些临床问题提供一个数值平台，并将有助于进一步研究鼻腔结构与鼻腔功能之间的关系。
