在本章中，作者描述了在真实环境中气味扩散的流体动力学考虑以及它们与使用嗅觉显示的真实气味呈现的关系。作者建议将计算流体动力学（CFD）模拟与嗅觉显示结合使用。利用CFD求解器计算了给定环境下的湍流气流场和气味分子的扩散。模拟结果用于重现气味浓度随时间和空间的真实变化。感官测试的结果，提出了一个示范cfd为基础的气味表现。讨论了室内环境中体温对气味扩散的影响及其对气味感知的影响。
In this chapter, the authors describe fluid dynamics considerations regarding odor dispersal in real environments and their relationship with realistic odor presentation using an olfactory display. The authors propose the use of a Computational Fluid Dynamics (CFD) simulation in conjunction with the olfactory display. A CFD solver is employed to calculate the turbulent airflow field in a given environment and the dispersal of odor molecules from their source. The simulation result is used to reproduce realistic changes in the odor concentration with time and space at the nose. The results of sensory tests are presented as a demonstration of CFD-based odor presentation. The effect of body heat on odor dispersal in indoor environments and how it affects odor perception is also discussed.
