Fluidic Chevrons for Jet Noise Reduction
Chevron mixing devices are used to reduce noise from commercial separate-flow turbofan engines. Mechanical chevron serrations at the nozzle trailing edge generate axial vorticity that enhances jet plume mixing and consequently reduces far-field noise. “Fluidic chevrons” generated with air injected near the nozzle trailing edge create a vorticity field similar to that of the mechanical chevrons ...
متن کاملMolecular simulation of chevrons in confined smectic liquid crystals.
Chevron structures adopted by confined smectic liquid crystals are investigated via molecular dynamics simulations of the Gay-Berne model. The chevrons are formed by quenching nematic films confined between aligning planar substrates whose easy axes have opposing azimuthal components. When the substrates are perfectly smooth, the chevron formed migrates rapidly towards one of the confining wall...
متن کاملEmpirical Doctrine
We can observe and measure how legal decision makers use formal legal authorities, but there is no way to empirically test the determinative capacity of legal doctrine itself. Yet discussions of empirical studies of judicial behavior sometimes conflate judges’ attention to legal rules with legal rules determining outcomes. Doctrinal determinacy is not the same thing as legal predictability. The...
متن کاملAn Analysis of Chevrons in Thin Liquid Crystal Cells
This paper is an analysis of a model for the structure in a liquid crystal medium that arises when the material is cooled from the smectic-A to the chiral smectic-C phase in a surface-stabilized cell with prescribed boundary conditions under a given electric field. This phenomenon causes V-shaped (chevron-like) defects to form in liquid crystal display devices and has attracted interest from bo...
متن کاملThe Doctrine of Signatures.
‘The Doctrine of Signatures’ started with the idea that God has marked everything he created with a sign (signature). The sign showed the purpose for the creation of the item. The ‘Doctrine of Signatures’ was promulgated by the writings of Jakob Böhme (1575–1624), a shoemaker in Görlitz, Germany, who had a profound mystical vision in which he saw a relationship between God and man that caused h...
