We present the results of the numerical simulation of the flow in the nasal cavity, going from the tip of the nostril to the nasopharyngeal region. The volume of the nasal cavity, obtained from axial and coronal scans, takes into account the geometries of the nasal valve and turbinates. The simulation is carried out with the FLUENT code which solves the equations of fluid mechanics. The obtained results for the inspiratory phase are analyzed from the velocities and pressures, paying special attention to the separation of the streamlines in the region located between the middle meatus and the olfactory area. The presented results show the potential of simulation when used in parallel with the clinical approach.
我们展示了从鼻孔尖端到鼻咽区域鼻腔内气流的数值模拟结果。通过轴向和冠状扫描获得的鼻腔容积，考虑了鼻瓣和鼻甲的几何形状。使用求解流体力学方程的FLUENT代码进行模拟。从速度和压力方面对吸气阶段获得的结果进行分析，特别关注中鼻道和嗅觉区域之间区域流线的分离。所展示的结果表明了模拟与临床方法并行使用时的潜力。
