“…Depending on the patient-specific anatomy of the nasal cavity, the location and shape of the vortices in the airway may change [21]. In the present study, the complex flow and vortices in the nasal valve region and immediately after the nasal valve are similar to experimental results of Doorly et al [19].…”

“…The advancement of CFD as well as the digital image processing sciences in the recent decades allows for a precise simulation of the nasal airflow and the particle dispersion and deposition pattern in the patient-specific nasal cavity. The first numerical studies of the airflow pattern in the nasal airway were accomplished by Keyhani et al [20] and Subramaniam et al [21]. Recently, particle dispersion and deposition have been studied in realistic nasal airways [22,23,24].…”

“…The total volume of the two compartments is adjusted equivalent to average volume of extra-thoracic of Indian women (Varghese et al, 2005). The volume-tosurface-area ratio is used for the calculation of the cross-sectional area based on Subramaniam et al (1998). Due to the complex nature of the NP region, deposition studies typically rely on empirical or logistic models.…”

“…Other studies have highlighted the physical significance of transient breathing (Shi et al, 2006), inlet velocity profiles (Keyhani et al, 1995;Subramaniam et al, 1998), nasal wall motion (Fodil et al, 2005), nasal valve change (Bridger 1970;Bridger and Proctor 1970) and glottal aperture variation (Brancatisano et al, 1983;. Moreover, each nasal model in this study is based on images of one single subject and does not account for the intersubject variability (Hilberg et al, 1993;Pickering and Beardsmore 1999).…”
