Oral Airway and Body Geometries for Cough Jet CFD: Models A, B, and C (v1.0)

We release human body models with anatomically detailed upper airways and oral cavities for CFD studies of cough jets and droplet/aerosol dispersion. Models A/B are realistic geometries; Model C is a simplified circular-orifice reference. Lip aperture, teeth, and palate are represented so the dataset supports time-resolved emission from inside the mouth (Eulerian Wall Film → Discrete Phase coupling) rather than instantaneous orifice seeding. Contents Model A: Realistic airway with narrow mouth opening (lips/teeth/palate included) Model B: Realistic airway with wide mouth opening (lips/teeth/palate included) Model C: Simplified circular mouth opening (no internal airway; reference model) Methods & provenance (cite with this dataset) If you use the these model, you must cite: Aboelsaud, M., Abouelhamd, I., Kuga, K., Inthavong, K., & Ito, K.
