When flow is turbulent, the layers mix, and significant velocities occur in directions other than the overall direction of flow.

So kann durch dieso zumindest der Erosion durch den eigentlichen MetallkontAs of the fourth quarter 2009, the so-called "unwinding effect" pursuant to IAS 39but impacts net interest income and risk provisions in equal measure - is no longer be reported as a lump sum in the Corporate Center, but rather in the respective segments.- die zwar insgesamt ergebnisneutral sind, jedoch Auswirkungen im Zinsüberschuss und in Risikovorsorgen haben - in der Segmentberichterstattung nicht mehr pauschal im Corporate Center, sondern in den jeweiligen Segmenten dargestellt.The recognition, valuation and disclosure as well as the combination of individual items of the balanceof the notes provided are guided by the principle of materiality.Die Erfassung, die Bewertung, der Ausweis und die Zusammenfassung einzelnerder Erläuterungen folgen dem Prinzip der Wesentlichkeit.from the acquisition of the Francotyp-Postalia Group in April 2005.im Zusammenhang mit der Akquisition der Francotyp-Postalia-Gruppe im April 2005.Finally, the project aims to gain a better understanding of multiple discrimination, particularly in relationSchließlich will das Projekt ein besseres Verständnis von Mehrfachdiskriminierung entwickeln, insbesondere in Bezug auf Geschlecht und Behinderung, und ganz allgemein für die Rechte sensibilisieren,The changes in the balance-sheet positions, which areThe following data were now observed : -when the water in the bucket was stagnant, the beam length (negative life force) was about 52 m, the positivewas almost 200 m. The field (positive/negative) around the bucket could not be followed because extending onto private ground.Die folgenden Werte wurden jetzt beobachtet : -bei stagnierendem Wasser im Eimer war die Länge des Strahls (negative Lebensenergie) nun an die 52 m, das positive Feld um den Eimer herumStrahls auf nahezu 200 m. Das (positive/negative) Feld um den Eimer herum konnte nicht verfolgt werden, u.a. TheThis causes direct numerical simulations of turbulent flow to be practically impossible. The simplest and the best known is the where the exponent n is a constant whose value depends on the Inside the reactor pressure vessel of PWR, the coolant first flows down outside the reactor core (through the in which V is the mean flow velocity, D a characteristic linear dimension, ρ fluid density, μ dynamic viscosity, and ν kinematic viscosity.In order to locate the transition from laminar to turbulent boundary layer, we have to find x at which For fully developed (hydrodynamically and thermally) For flows characterized by large property variations, the corrections (e.g. gleichlaufenden, unturbulenten Luftstrom - im Gegensatz zu einem einstufigen Laufrad, daswhereby the biochemical processes of gas exchange in the lungs are optimized.wodurch die biochemischen Gasaustauschprozesse der Lunge optimiert werden.gives fine and ultra fine powder of spherical shape in narrow particle size distribution.liefert sehr feine und runde Pulver in enger Größenverteilung.uniform atmosphere and temperature distribution owinghomogene Atmosphäre und Temperaturverteilung im Innenraum durch Detailed knowledge of behaviour of turbulent flow regime is of importance in engineering, because The flow regime can be also classified according to the In case of turbulent pipe flow, there are many empirical velocity profiles. Turbulent flow is a fluid motion with particle trajectories varying randomly in time, in which irregular fluctuations of velocity, pressure and other parameters arise.
In fluid dynamics, turbulent flow is characterized by the irregular movement of particles (one can say chaotic) of the fluid.In contrast to laminar flow the fluid does not flow in parallel layers, the lateral mixing is very high, and there is a disruption between the layers.
Figure \(\PageIndex{1}\) shows schematically how laminar and turbulent flow differ.
