The effect of variation of nasal structure on airflow distribution was investigated. Based on the CT images of the nose of a healthy female, a three-dimensional nasal model was developed. Two new nasal models were produced by removing part of inferior turbinate and part of middle turbinate in the left side of the original model. The numerical simulation and analysis for airflow field in the three nasal models was conducted by the finite element method. The simulation results from new models were compared with those from the original model. The airflow rate changed in the two sides of new nasal models. The airflow distribution and the pressure grades varied in the side of nasal model where part of inferior turbinate or part of middle turbinate was removed. The variation of nasal cavity structure will result in airflow redistribution in nasal cavity. The effect of removing turbinate on the airflow distribution in nasal cavity was described quantitatively.
研究了鼻腔结构变化对气流分布的影响。基于一名健康女性的鼻部CT图像，构建了三维鼻腔模型。通过去除原始模型左侧部分下鼻甲和部分中鼻甲，生成了两个新的鼻腔模型。采用有限元方法对三个鼻腔模型的气流场进行了数值模拟和分析。将新模型的模拟结果与原始模型的结果进行了比较。新鼻腔模型两侧的气流速率发生了变化。在去除部分下鼻甲或部分中鼻甲的鼻腔模型一侧，气流分布和压力等级有所不同。鼻腔结构的变化将导致鼻腔内气流重新分布。定量描述了去除鼻甲对鼻腔气流分布的影响。
