  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. Boundary conditions in fluid dynamics - Wikipedia

    en.wikipedia.org/wiki/Boundary_conditions_in...

    Showing wall boundary condition. The most common boundary that comes upon in confined fluid flow problems is the wall of the conduit. The appropriate requirement is called the no-slip boundary condition, wherein the normal component of velocity is fixed at zero, and the tangential component is set equal to the velocity of the wall. [1]

  4. Boundary layer - Wikipedia

    en.wikipedia.org/wiki/Boundary_layer

    The no-slip condition requires the flow velocity at the surface of a solid object be zero and the fluid temperature be equal to the temperature of the surface. The flow velocity will then increase rapidly within the boundary layer, governed by the boundary layer equations, below.

    Fig 1 Formation of grid in cfd. Almost every computational fluid dynamics problem is defined under the limits of initial and boundary conditions. When constructing a staggered grid, it is common to implement boundary conditions by adding an extra node across the physical boundary.

  7. Rayleigh problem - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_problem

    The initial and the no-slip condition on the wall are (,) =, (, >) =, (, >) =, the last condition is due to the fact that the motion at = is not felt at infinity. The flow is only due to the motion of the plate, there is no imposed pressure gradient.

  8. Stokes problem - Wikipedia

    en.wikipedia.org/wiki/Stokes_problem

    The initial, no-slip condition on the wall is (,) = ⁡, (,) =, and the second boundary condition is due to the fact that the motion at = is not felt at infinity. The flow is only due to the motion of the plate, there is no imposed pressure gradient.

  9. Hagen–Poiseuille equation - Wikipedia

    en.wikipedia.org/wiki/Hagen–Poiseuille_equation

    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: = (). The maximum velocity occurs at the pipe centerline (r = 0), u max = ⁠ GR 2 / 4μ ⁠.
