abstract = {Abstract Impaired respiration capabilities or a reduced
sense of smell and taste are common for pathologically
shaped nasal cavities. To analyze the flow in the human
nasal cavity, simulations with a Lattice-Boltzmann Method
(LBM) are carried out. This method is particularly suited to
simulate flows in intricate geometries, it is efficient
compared to solvers based on the Navier-Stokes equations,
and straight forward to parallelize. A surface of the nasal
cavity is extracted from Computer Tomography (CT) images and
is used to automatically generate a hierarchically refined
computational grid. Wall-bounded shear layers are highly
resolved in contrast to re- gions of lower velocity
gradients. In this way the overall number of cells is
reduced and the computational efficency is improved. A mean
volume flux of 125 ml/sec is prescribed, which results in a
REYNOLDS number of Re = 766 based on the averaged velocity
and the averaged hydraulic diameter of the nostrils of the
nasal cavity. Different nasal cavities are investigated,
previously selected from medical analysis. A performance
analysis of the algorithm is carried out to show the
scalability of the code. The findings verify that the LBM
is a valuable tool to predict and analyze the flow in the
human nasal cavity for the individual patient and that it is
suited for High Performance Computing (HPC) due to its good
scalability.},
