  2. No-slip condition - Wikipedia

    en.wikipedia.org/wiki/No-slip_condition

    The no-slip condition is an empirical assumption that has been useful in modelling many macroscopic experiments. It was one of three alternatives that were the subject of contention in the 19th century, with the other two being the stagnant-layer (a thin layer of stationary fluid on which the rest of the fluid flows) and the partial slip (a finite relative velocity between solid and fluid ...

  3. Stokes problem - Wikipedia

    en.wikipedia.org/wiki/Stokes_problem

    The case for an oscillating far-field flow, with the plate held at rest, can easily be constructed from the previous solution for an oscillating plate by using linear superposition of solutions. Consider a uniform velocity oscillation u ( ∞ , t ) = U ∞ cos ⁡ ω t {\displaystyle u(\infty ,t)=U_{\infty }\cos \omega t} far away from the ...

  4. Boundary layer - Wikipedia

    en.wikipedia.org/wiki/Boundary_layer

    In physics and fluid mechanics, a boundary layer is the thin layer of fluid in the immediate vicinity of a bounding surface formed by the fluid flowing along the surface. The fluid's interaction with the wall induces a no-slip boundary condition (zero velocity at the wall). The flow velocity then monotonically increases above the surface until ...

  5. Navier–Stokes existence and smoothness - Wikipedia

    en.wikipedia.org/wiki/Navier–Stokes_existence...

    In mathematics, the Navier–Stokes equations are a system of nonlinear partial differential equations for abstract vector fields of any size. In physics and engineering, they are a system of equations that model the motion of liquids or non-rarefied gases (in which the mean free path is short enough so that it can be thought of as a continuum mean instead of a collection of particles) using ...

  6. Dirichlet boundary condition - Wikipedia

    en.wikipedia.org/wiki/Dirichlet_boundary_condition

    In mathematics, the Dirichlet boundary condition is imposed on an ordinary or partial differential equation, such that the values that the solution takes along the boundary of the domain are fixed. The question of finding solutions to such equations is known as the Dirichlet problem .

  7. Talk:No-slip condition - Wikipedia

    en.wikipedia.org/wiki/Talk:No-slip_condition

    This page needs a simple and yet complex explanation of no slip condition, as it is only those who know a thing or two about fuild flow will understand this page, and i don't mean know a thing or two as in the water flows down the pipe. —Preceding unsigned comment added by 208.79.15.101 21:00, 20 May 2008 (UTC)

  8. Hagen–Poiseuille equation - Wikipedia

    The solution is = + ⁡ + Since u needs to be finite at r = 0, c 1 = 0. The no slip boundary condition at the pipe wall requires that u = 0 at r = R (radius of the pipe), which yields c 2 = ⁠ GR 2 / 4μ ⁠. Thus we have finally the following parabolic velocity profile:

  9. Three-body problem - Wikipedia

    An animation of the figure-8 solution to the three-body problem over a single period T ≃ 6.3259 [13] 20 examples of periodic solutions to the three-body problem In the 1970s, Michel Hénon and Roger A. Broucke each found a set of solutions that form part of the same family of solutions: the Broucke–Hénon–Hadjidemetriou family.
