An olfactory display is a device that delivers various odors to the user's nose. It can be used to add special effects to movies and virtual reality systems by releasing odors relevant to the scenes shown on the screen. To provide high-presence olfactory stimuli to the user, the olfactory display must be able to generate realistic smells with appropriate intensities in a timely manner. Here we propose to use computational fluid dynamics (CFD) simulations in conjunction with the olfactory display. In the proposed system, a CFD solver is employed to calculate the turbulent airflow field in the given environment and the dispersal of odor molecules from their source. An odor blender is used to generate the odor with the concentration determined based on the calculated odor distribution. Experimental results on presenting odor stimuli synchronously with a movie clip and generating odor stimuli together with a changing airflow field show the effectiveness of the proposed system for the delivery of high-presence olfactory stimuli.
