Flujo alrededor de un obstáculo; el flujo aguas arriba es laminar. Turbulencia en el vórtice de punta en el ala de un avión. En términos de la dinámica de fluidos, turbulencia o flujo turbulento es un régimen de flujo caracterizado por baja difusión de momento, alta convección y cambios espacio-temporales rápidos de presión y velocidad.
In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to a laminar flow , which occurs when a fluid flows in parallel layers, with no disruption between those layers.
3 de mar. de 2023 · In air travel, turbulence is a certainty and a major source of flight anxiety for flyers of all stripes. But understanding what causes turbulence, where it occurs, and the high-tech...
22 de may. de 2024 · Turbulence, In fluid mechanics, a flow condition (see turbulent flow) in which local speed and pressure change unpredictably as an average flow is maintained. Common examples are wind and water swirling around obstructions, or fast flow (Reynolds number greater than 2,100) of any sort.
19 de mar. de 2021 · Turbulent fluid dynamics are literally all around us. This video describes the fundamental characteristics of turbulence with several examples from nature and from engineering. We discuss how ...
1 de oct. de 2005 · The first three chapters of Turbulence give a clear introduction to the classical picture of turbulence. Chapter 4 concerns turbulent shear flows and simple closure models. In chapters 5 through 8, the author develops the physics of homogeneous isotropic turbulence in further detail.
1 de ene. de 2015 · This first chapter illustrates the interest of turbulent flows. Numerous definitions and general concepts are introduced to characterize turbulence. Some practical consequences are also briefly described. On the whole, transport is very efficient in a turbulent flow, be it for momentum, mass or heat.
