Abstract
Whether the drug is successfully transported to the focus area is the key to the treatment of the rhinitis disease. The efficiency of drug delivery is dependent on the design of nasal spray device. A three-dimensional model of nasal cavity was constructed from the head CT image data of a healthy human subject. The deposition of drug particles was simulated numerically by Computational Fluid Dynamics technique. The main variables of the study were the size and density of drug particles, the injecting speed of drugs etc. In conclusion, with the increase of particle intensity and injection speed, the deposition of particles in the affected area trends to increase after first slow decrease.
