15 صفحه اولUnsteady Particle Deposition in a Human Nasal Cavity
The deposition efficiency of unsteady inhalation is investigated in present study by using computational fluid dynamics techniques. Comparison with steady inhalation is also discussed. The inspiratory cycle of a realistic unsteady inhalation profile was applied at the outlet of nasopharynx, which has the maximum flow rate of 40.3L/min. Aerodynamic particle sizes of 5μm and 20μm were studied in ...
متن کاملApplication of surface mapping to visualize wall shear stress and particle deposition in realistic human nasal cavities
Nasal cavity is an important component of respiration system for the various physiological functions (Elad et al., 2008; Lee, 2010). Due to its complicated geometry, flow patterns are difficult to visualize inside 3D spaces. By adopting the ISOMAP algorithm (Tenenbaum et al., 2000) implemented in Matlab, the surface of a nasal cavity, together with characteristic lines serving as visual markers...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
