Numerical Simulation of the Dispersion and Deposition of a Spray Carried by a Pulsating Airflow in a Patient-Specific Human Nasal Cavity

Abstract: The present numerical study concerns the dispersion and deposition of a nasal spray in a patient-specific human nose. The realistic three-dimensional geometry of the nasal cavity is reconstructed from computer tomography (CT) scans. Identification of the region of interest, removal of artifacts, segmentation, generation of the .STL file and the triangulated surface grid are performed using the software packages ImageJ, meshLab, and NeuRA2. An unstructured computational volume grid with approximately 15 million… Show more

“…With the development of computational resources, more researchers begin using numerical analysis and CFD to investigate nasal flows [4,5,6,7,8,9]. More recently, CFD was used to investigate different aspects of nasal flow: particle deposition in steady and pulsating flows [10,11], improving nasal surgery results by investigating the effects of surgical procedures [12], Large Eddy Simulation (LES) of water droplet deposition and assessment of nasal obstructions [13]. While most of the aforementioned studies relied on proprietary software for meshing and numerical analysis, Tretiakow et al [14] used OpenFOAM to perform a series of CFD simulations of airflow in the nasal cavity and paranasal sinuses.…”
