Definition von streamlines im Englisch Englisch wörterbuch
(n) Line marks, usually curved, used in visualizations to depict the path of flow of a fluid or gas Streamlines are used in aerodynamic studies to evaluate the flow of air or water around a proposed design
A method for outlining the topology, i e the field lines, of a vector field One takes a set of starting points, finds the vectors at these points by interpolation, if necessary, and integrates the points along the direction of the vector At the new positions the vector values are found by interpolation and one integrates again This process stops if a predetermined number of integration steps has been reached or if the points end up outside the data volume The calculated points are connected by lines The streamlines technique considers the vector field to be static
a type of fluid flow in which each layer of fluid follows a smooth path past other layers without crossing over or becoming tangled (also called laminar flow)
to a stream line; designating a motion or flow that is free from turbulence, like that of a particle in a streamline; hence, designating a surface, body, etc
Streamlines of flow about a streamline body follow the contours of the body In streamline bodies the flow remains attached, whilst keeping wake behind it to a minimum
1 A body position that permits the smooth and efficient passage of water along your body as you swim, thus minimizing your drag in the water An important consideration in every stroke! 2 A low-drag body position in which the arms are extended straight ahead, usually with the hands placed one atop the other or palm-to-palm Used mainly during kick drills and immediately after turns (before breakout)
In visualization, an instantaneous representation of a vector field In contrast to Streakline, the path of a Styrofoam ball or balls over time through a static vector field For example, if you released a set of balls at the top of a hill, and assume the hill gradient is not changing over the brief time of sampling, the same paths would be traced by balls released at the same points now and one hour from now (disregarding chaos theory) Videotaping their motion with an open shutter would yield a line showing the overall path through the static gradient
To streamline an organization or process means to make it more efficient by removing unnecessary parts of it. They're making efforts to streamline their normally cumbersome bureaucracy. In fluid mechanics, the path of imaginary particles suspended in the fluid and carried along with it. In steady flow, the fluid is in motion but the streamlines are fixed. Where streamlines crowd together, the fluid speed is relatively high; where they open out, the fluid is relatively still. See also laminar flow, turbulent flow
