Anatomically accurate 3D models of 10 healthy nasal cavities are developed from computerized tomography (CT) scan images. Considering anatomical and physiological importance of different parts of the nasal cavity, the surface of each nasal passage is divided to eleven anatomical surfaces. Also the coronal cross sections in the nasal passage are divided to six sub-sections that share the total nasal passage airflow. The details of the flow field, heat transfer and water-vapor transport are numerically investigated for resting and low activity conditions. The mean and standard deviation of the different anatomical and air conditioning parameters such as: surface area, wall shear stress, heat and moisture transfer on different parts of the nasal passage surfaces and volume flow rates through different sections are presented. Results show that the percentages of airflow for inferior, middle and superior meatuses are 11.3 ± 6.4, 36.5 ± 9.5, 1.9 ± 0.81 % respectively and 4.1 ± 2.1 % of air passes through olfactory area. The inhaled air passing from the remaining surface (main passage) is 46.2 ± 10 %. Heat and moisture fluxes are highest in the anterior part of the nasal cavity, turbinates and lower part of the septum respectively. The percentage of the heat transfer from turbinates is 25.7 ± 3.9 % of total nasal heat transfer.

10 个健康鼻腔的解剖学准确 3D 模型是根据计算机断层扫描 (CT) 扫描图像开发的。考虑到鼻腔不同部位在解剖学和生理学上的重要性，每个鼻道的表面被分为十一个解剖表面。此外，鼻道中的冠状横截面被分成六个子部分，它们共享总的鼻道气流。在静止和低活动条件下，对流场、传热和水汽传输的细节进行了数值研究。呈现了不同解剖和空调参数的平均值和标准偏差，例如：表面积、壁面剪应力、鼻道表面不同部位的热量和水分传递以及通过不同截面的体积流量。结果表明，下、中、上口的气流百分比分别为11.3±6.4、36.5±9.5、1.9±0.81%，4.1±2.1%的空气通过嗅觉区。从其余表面（主通道）通过的吸入空气为 46.2 ± 10 %。鼻腔前部、鼻甲和鼻中隔下部的热量和水分通量分别最高。鼻甲传热的百分比为鼻总传热的 25.7 ± 3.9 %。鼻甲和鼻中隔的下部。鼻甲传热的百分比为鼻总传热的 25.7 ± 3.9 %。鼻甲和鼻中隔的下部。鼻甲传热的百分比为鼻总传热的 25.7 ± 3.9 %。
