Turbulent diffusion was the dominant transport mechanism for particles less than 1 渭m, where deposition decreased with particle size. Two major deposition sites were visualized with radio-aerosol in the anterior region of the nasal airway. One is close to the ostium internum where turbulent eddies...
However, the deposition mechanism is not fully understood. In addition, many technical challenges have been observed for achieving a successful deposition of the oxides with higher efficiency. In this work, the influence of different processing parameters on the properties of the deposited layer is ...
THE deposition of aerosols in the lungs of man during breathing constitutes an important mechanism for the entry of toxins or pathogenic organisms to the body. The respiratory tract is protected by an efficient ciliary mechanism for the rapid removal of particles deposited in the upper airways. ...
A detailed deposition mechanism has described the AA-MOCVD process. The resistance measurement of electrochemical cell Pt/Ni-YDC/YSZ film/Pt showed that conductivity activation energy (Ea) changed at 610 °C with 85.8 kJ/mol at 610–850 °C and 136 kJ/mol at 350–610 °C. ...
trapping in each generation were recorded. The results indicate that there are dramatic differences in the predicted deposition between the two models. The intragenerational deposition locations show that in regions where the deposition mechanism is inertial impaction, the predominant deposition seems to ...
The mechanism of deposition was consistent with diffusion through a boundary layer during filling followed by sedimentation of the remaining suspended aerosol particles. Based on these results, an aerosol with a median particle size of 1.3 碌m was shown to provide a therapeutically effective dose of...
Turbulence is an efficient mechanism of transporting aerosols both within the PBL and into the free troposphere (FT). Regional and global air pollution/climate models are typically used for air quality and climate assessments, although the fundamental interactive processes between aerosols, clouds, and...
1) aerosol deposition AD法 1. Theaerosol deposition(AD) method,which falls into the category of thermal spray technique,is a coating preparation method that has come into being just recently. 气浮沉积法简称AD法,是一种新近开发的表面涂层制备方法,属于热喷涂技术范畴。
For turbulent flows, the phenomenology changes where the turbulence brings particles close enough to the wall for diffusion to become the dominant transport mechanism and lead to particle deposition; the codes VICTORIA and ASTEC concur, again, in the use of the same model, that of Davies [65]....
Atmospheric aerosol deposition is an important source of nutrients and pollution to many continental and marine ecosystems. Humans have heavily perturbed the cycles of several important aerosol species, potentially affecting terrestrial and marine carbon budgets and consequently climate. The most ecologically...
