Numerical simulation of the flow field in a model of the nasal cavity

Abstract Results of a numerical simulation of the flow in a model of the human nasal cavity using an AUSM-based method of second-order accuracy on a multi-block structured grid are presented and compared with experimental data. Computations are performed for inspiration and expiration at rest with Reynolds numbers Re =1560 and Re =1230 at the nostril, respectively. The comparison shows good agreement with experimental findings.
