In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to laminar flow , which occurs when a fluid flows in parallel layers with no disruption between those layers.
The United States has gone through several party systems, where in each system, the two main parties have characteristic platforms and constituencies. Likewise, the United States has had several realigning elections, elections that bring fast and large-scale changes. These events are mentioned here because their repeated occurrence may be ...
Although the vast majority of cases of turbulence are harmless, in rare cases cabin crew and passengers on aircraft have been injured when tossed around inside an aircraft cabin during extreme turbulence. In a small number of cases, people have been killed and at least two aircraft disintegrated mid-air.
One passenger died and 30 others were injured aboard a Singapore Airlines flight that was hit by "severe turbulence," officials said Tuesday, but experts say such deaths are rare even as ...
The propensity of a fluid to swirl is used to promote good fuel/air mixing in internal combustion engines.. In fluid mechanics and transport phenomena, an eddy is not a property of the fluid, but a violent swirling motion caused by the position and direction of turbulent flow.
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
Seven people were hurt, none seriously, after a United Airlines plane headed to a New York City-area airport experienced high winds and turbulence. 7 hurt after Newark-bound United flight ...
SST (Menter's shear stress transport) turbulence model [11] is a widely used and robust two-equation eddy-viscosity turbulence model used in computational fluid dynamics. The model combines the k-omega turbulence model and K-epsilon turbulence model such that the k-omega is used in the inner region of the boundary layer and switches to the k ...
