The flow characteristics and heat transfer during nasal breathing in the complete human upper airway were investigated through respiratory cycle using transient numerical simulations. We postulate that from cavity to trachea most accurately represents dynamic airflow patterns inhalation exhalation as they are likely be affected by downstream anatomical structures. A 3D model was constructed a healthy adult computed tomography scan. Computational fluid dynamics simulations performed with...
Computational studies of micron particle deposition is used to predict inhaled particles through the nasal cavity for understanding drug delivery or toxicology risks. To ensure reliable results in future studies, this study evaluated tracking schemes and determined most appropriate settings predicting a pipe bend geometry.Micron were injected into fully developed 90° under turbulent flow regime with Reynolds number, Re = 10 000, comparison existing data literature. Similarly, released more...
Respirators provide protection from inhalation exposure to dangerous substances, such as chemicals and infectious particles, including SARS-COVID-laden droplets aerosols. However, they are prone stale air masks create a microclimate influenced by the exhaled air. As result, lungs accumulating in mask produces warm humid environment that has high concentration of carbon dioxide (CO2), unsuitable for re-inhalation. Fans favorable option respirators ventilate remove This study utilized...
Nasal adhesions (NAs) are a known complication of nasal airway surgery. Even minor NAs can lead to significant postoperative obstruction (NAO). Division such often provides much greater relief than anticipated.We examine the impact at various anatomical sites on airflow and mucosal cooling using computational fluid dynamics (CFD) multiple test subjects.CT scans healthy adult subjects were used construct three-dimensional models. A single virtual 2.5 mm diameter NA was placed one five...
