Flow attenuation definition
WebFor the open spunlaid process, the attenuation air is a separate source, whereas the attenuation air in the closed process is the same as the cooling air going through the quench chambers. In an open system, the cooling and attenuation of the filaments can be adjusted independently. In closed processes, these two process steps are coupled.

WebMay 9, 2024 · At the same time, the shear generated bottom stress due to the tidal current is weak as the flow switches from ebb to flood. As water depth increases, attenuation of the orbital velocities with depth decreases the bottom shear stress of the vessel wake, while the current shear stress increases until maximum flood.

WebEarly selection models of attention [ edit] The early selection model of attention, proposed by Broadbent, [1] posits that stimuli are filtered, or selected to be attended to, at an early stage during processing. A filter can be regarded as the selector of relevant information based on basic features, such as color, pitch, or direction of stimuli.
