Here we explore possibilities of the detached eddy simulation models (DES-models) in relation to a human nasal cavity as to a complicated structure of variable section with several bulges and irregularities (paranasal sinuses and turbinate). The three-dimensional geometric model (3D-model) of nasal cavity is perfomed on the results of the computer tomography with the Mercury Amira soft. The convective flows in the 3D-model are given with the Ansys Icem CFD soft. First-ever the nonstationary flow calculations for the 3D-model simulated nasal cavity are performed which aren’t averaged in time, and consider the function of pressure drop in breathing. The results of the simulation are compared with the experimental data obtained for the analogous solid 3D-model.
