What is the mystery of turbulence? - Physics Stack Exchange Turbulence is not one of the great unsolved problems in physics Physics tells us exactly how turbulence emerges as a direct consequence of local mass and momentum conservation We can create multiparticle computer models such as lattice gas automata that generate turbulence at large length and time scales
fluid dynamics - Is turbulence more likely to form with the Euler . . . Wiki states on turbulence: Turbulence is the time-dependent chaotic behaviour seen in many fluid flows It is generally believed that it is due to the inertia of the fluid as a whole: the culmination of time-dependent and convective acceleration;
What are the length and time scales in turbulence? Basically, the scale of a certain parameter is the order of magnitude of that parameter Being able to determine the scales of a parameters in a complex system (like turbulence problems) is very useful
Is there anything more chaotic than fluid turbulence? Fluid turbulence is a highly complex and non-linear chaotic phenomenon Great difficulties and complications are encountered when trying to accurately and robustly calculate or simulate fluid flows, due to the chaotic, multi-scale effects of turbulence
Taylors hypothesis in turbulence - Physics Stack Exchange The "Taylor Hypothesis" is founded on the idea that the changes observed in any given plasma measured in the solar wind propagate at speeds much much less than the bulk flow speed of the solar wind (well, this has been applied in other regions of space than just the solar wind, but it's most commonly assumed there)
What does “eddy” mean in turbulence? - Physics Stack Exchange a newbie in turbulence study, very confused about the concept of eddy, I feel the word quot;eddy quot; having two meanings in fluid-mechanics maybe more and i'm not sure if i understand correctly
fluid dynamics - Can Increasing the Turbulence Inside a Pipeline . . . The efficiency of the turbulence would likely be velocity dependent Relevant Information: The Darcy-Weisbach equation is used to describe the pressure loss over a given segment of pipe Blatt, Middleton, and Murray, " Origin of Sedimentary Rocks ," 2nd Ed
Why turbulence is non-equilibrium? - Physics Stack Exchange I've encountered this notion many times that turbulence is non-equilibrium (e g , Falkovich amp; Sreenivasan, Physics Today, 59, 2006) However, I am confused about what does it mean by "non-
Fractal nature of turbulence - Physics Stack Exchange But outside this area, picture is quite different For larger scales flow is non universal and is governed by global geometry of boundary For smaller scales than inertial, flow is governed by decay down to thermal scales Turbulence is strongly nonlinear and very complicated phenomenon and selfsimilarity describes it only in partial way
fluid dynamics - Can a vacuum make a turbulent flow laminar? - Physics . . . $\begingroup$ Turbulence arises not when laminar flow is not "possible", but when it is not stable So a reasoning like "I could devise laminar flow lines for the setup" does not allow to determine whether there'll be turbulence of not $\endgroup$ –
