The airman, who has been in the service for about 10 years, initially crossed out the line when recently signing the Defense Department form required for re-enlistment. In a seeming reversal of the Air Force’s previous stance that the “So help me God” portion was optional, the airman ...
There are two key factors in suppressing deflection of the expanding lamella: (1) the induced dielectrophoretic force pulls the advancing lamella down against a combination of aerodynamical lift on top of the expanding lamella and lubrication force in the air underneath30and (2) the spatial variati...

2010). This phenomenon causes an intense loss in the osmotic driving force (McCutcheon and Elimelech 2008), and since it occurs in the support layer, it cannot be removed by increasing the flow rate turbulence (Zhao et al. 2012a). With the intention to minimize the ICP problem, it was ...
Under the strong centrifugal force generated by the high-speed rotating turbine, the materials are separated and the fine particles which meet size requirements through the classifier impeller gap into the cyclone separator or the dust collector, ...
The classifier and cyclone separator, dust collector and induced draft fan form a classifying system.Under the action of fan suction, the material is moved from the lower inlet of the classifier to the classifying zone with the ascending airflow. Under the strong ce...
Decisions about where to site new power plants are influenced by many factors including the cost of land, wages, available labour force, access to transportation and water, local and state regulations and community and political resistance31. The associations between red-lining and power plant ...
The Ekman layeris the layer in a fluid where force balance between pressure gradient force, turbulent drag and coriolis force are balanced. It was named after scientist Vagn Walfrid Ekman who explained the phenomena for the first time. Ekman layer extends to height of 300–500 m. In this la...
- An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate. - The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence ...
