In the aircraft example, the observer on the ground will observe unsteady flow, and the observers in the aircraft will observe steady flow, with constant streamlines. When possible, fluid dynamicists try to find a reference frame in which the flow is steady, so that they can use experimental methods of creating streaklines to identify the ...
Because = everywhere (e.g., see In terms of vector rotation), each streamline corresponds to the intersection of a particular stream surface and a particular horizontal plane. Consequently, in three dimensions, unambiguous identification of any particular streamline requires that one specify corresponding values of both the stream function and ...
Streamline Moderne is an international style of Art Deco architecture and design that emerged in the 1930s. Inspired by aerodynamic design, it emphasized curving forms, long horizontal lines, and sometimes nautical elements. In industrial design, it was used in railroad locomotives, telephones, buses, appliances, and other devices to give the ...
Example 3.5 and p.116 The following assumptions must be met for this Bernoulli equation to apply: [2]: 265 the flow must be steady, that is, the flow parameters (velocity, density, etc.) at any point cannot change with time, the flow must be incompressible—even though pressure varies, the density must remain constant along a streamline;
The ψ = 0 streamline is particularly interesting: it has two (or four) branches, following the coordinate axes, i.e. x = 0 and y = 0. As no fluid flows across the x-axis, it (the x-axis) may be treated as a solid boundary. It is thus possible to ignore the flow in the lower half-plane where y < 0 and to focus on the flow in the upper halfplane ...
Family command centers are designed to streamline schedules and stuff, ... For example, one day you can take on the kitchen cabinets, another the drawers, and a third the pantry.
Since a streamline is a curve that is tangent to the velocity vector of the flow, the left-hand side of the above equation, the convective derivative of velocity, can be described as follows: = = +, where =,, =, and is the radius of curvature of the streamline.
The FHA streamline refinance program makes it easier and cheaper for borrowers who have a Federal Housing Administration-insured mortgage to refinance their loans at lower rates. ... for example ...
