Streamlined objects and organisms, like airfoils, streamliners, cars and dolphins are often aesthetically pleasing to the eye. The Streamline Moderne style, a 1930s and 1940s offshoot of Art Deco, brought flowing lines to architecture and design of the era. The canonical example of a streamlined shape is a chicken egg with the blunt end facing ...
Streamline style can be contrasted with functionalism, which was a leading design style in Europe at the same time. One reason for the simple designs in functionalism was to lower the production costs of the items, making them affordable to the large European working class. [ 18 ]
These fish also tend to have "flatter" bodies which increase the total lift producing area thus allowing them to "hang" in the air better than more streamlined shapes. [21] As a result of this high lift production, these fish are excellent gliders and are well adapted for maximizing flight distance and duration.
The rounded shapes of one or both ends of the Sterling Streamliner diners resembled the sloping curved nose of the Burlington Zephyr's streamlined silver locomotive. [ 66 ] [ 67 ] One such Sterling Streamliner with two rounded ends was built in 1940 and installed as the Jimmy Evans Flyer in New Bedford, Massachusetts .
In fluid mechanics, kinematic similarity is described as “the velocity at any point in the model flow is proportional by a constant scale factor to the velocity at the same point in the prototype flow, while it is maintaining the flow’s streamline shape.” [1] Kinematic Similarity is one of the three essential conditions (Geometric Similarity, Dynamic Similarity and Kinematic Similarity ...
Like a streamline, a stream surface is used to visualize flows – three-dimensional flows in this case. Specifically, it is "the locus of an infinite set of such curves [streamlines], rooted at every point along a continuous originating line segment."
Article covers many important aspects, but still needs more figures showing different streamline/streakline patterns in flows. Possibility of adding timeline which are also used to describe/visualize a flow. Timeline describes the deformation of adjacent fluid particles as they move around. Sketch showing different types of lines in a flow field.
Since =, the streamline patterns in the -plane thus correspond to potential flow (irrotational flow). Unlike potential flow , here the circulation Γ {\displaystyle \Gamma } around any closed contour C {\displaystyle C} (parallel to the x y {\displaystyle xy} -plane), whether it encloses a solid object or not, is zero,
