abstract = {A numerical study using the lattice-Boltzmann method is
conducted to investigate the conditioning ability of the
human nose, where a boundary treatment is implemented to
model the latent heat effect. The humidity exchange at the
wet surface of the nasal mucosa influences the wall
temperature, imitating the thermal inertial effects of the
mucosa tissue. To capture the curvature of the cavity
geometry, interpolated bounce-back schemes are used to set
the wall temperature and water concentration computed by the
boundary model. The impact of evaporation on the
conditioning ability is investigated for pre- and
post-surgery cavity geometries of a patient that was
diagnosed with enlarged turbinates and underwent
turbinectomy. The widening of the nasal passages in the
course of the turbinectomy cause a reduced pressure loss
between the inlets (nostrils) and the outlet (pharynx), but
also dry air streaming towards the back part of the
airway-throat interface. This coincides with the patient’s
perception, who reported less efforts for breathing in, but
at the same time a dry and sometimes painful feeling at the
back of the throat.},
