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 ...
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 ...
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 ...
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 ...
For example, the Obama ... The CEQ's interim rule may reduce NEPA-caused bureaucracy, which is sorely needed to streamline permitting in the United States. The Trump administration should go ...
The second equation expresses that, in the case the streamline is curved, there should exist a pressure gradient normal to the streamline because the centripetal acceleration of the fluid parcel is only generated by the normal pressure gradient. The third equation expresses that pressure is constant along the binormal axis.
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 ...
