Encyclopedia > Transition point

In the field of fluid dynamics the point at which the boundary layer changes from laminar to turbulent is called the transition point. Where the boundary layer becomes turbulent, drag due to skin friction is relatively high. As speed increases, the transition point tends to move forward. As the angle of attack increases, the transition point also tends to move forward. This article or section should be merged with Fluid mechanics Fluid dynamics is the study of fluids (liquids and gases) in motion, and the effect of the fluid motion on fluid boundaries, such as solid containers or other fluids. ... The boundary layer is the layer of fluid in the immediate vicinity of a bounding surface. ... laminar and turbulent water flow over the hull of a submarine In fluid dynamics, laminar flow is a flow regime characterized by high momentum diffusion, low momentum convection, and pressure and velocity independence from time. ... Turbulent flow around an obstacle; the flow further away is laminar Laminar and turbulent water flow over the hull of a submarine Turbulence creating a vortex on an airplane wing In fluid dynamics, turbulence or turbulent flow is a flow regime characterized by low-momentum diffusion, high momentum convection, and... The word drag has several meanings: In physics, drag is a combination of aerodynamic or hydrodynamic forces. ... In Aerodynamics, skin friction is the component of parasitic drag arising from the friction of the fluid against the skin of the object that is moving through it. ... In this diagram, the black arrow represents the direction of the wind. ...

Global Positioning System - Wikipedia, the free encyclopedia (6603 words)
The first satellite navigation system, Transit, used by the United States Navy, was first successfully tested in 1960.
The time delay is calculated by increasingly delaying the local signal and comparing it to the one received from the satellite; at some point the two signals will match up, and that delay is the time needed for the signal to reach the receiver.
The problem arises because the transition from 0-1 or 1-0 on the C/A signal is not instantaneous, it takes a non-zero amount of time, and thus the correlation (satellite-receiver sequence matching) operation is imperfect.
ON QUANTUM THEORETICAL ORIGINS OF NEWTONIAN TIME (15429 words)
Moreover, if the j transitions are ordered by labels (1, 2, 3,..., j) in each term, we also cannot know the order of any specifically labeled transitions; therefore, we divide the jth degree term by the number of permutations of the labeled transitions, j!.
This distinguishes n=4 as a transition point, where in the local quantum temporal behavior, order in the transitions of the fundamental clock eigenprocesses emerges from their "q-stochastic chaos".
In this view point of dynamics from transition amplitudes, there is an intrinsic and absolute proper waiting time that is counted in indivisible Planck time units, which act much like refractory periods after which either a transition takes place, or doesn't.
