Abstract Nasal cavity is an important component of respiration system for the various physiological functions (Elad et al., 2008; Lee, 2010). By using a commercial CFD software Ansys-Fluent and a surface mapping software Unfold3D, wall shear stress (WSS) distribution and particle deposition patterns on the nasal cavity wall were simulated and transformed into a normalized UV domain (where U and V denote coordinate axes of a 2D space) to present a complete view of an entire wrapped surface, therefore to be analyzed with better precision and to allow direct comparisons between left and right cavities. In this paper, applications of surface mapping methods on a nasal cavity are demonstrated, and results for WSS distribution and time dependent particle deposition on UV domain during steady inhalation are analyzed.
