  2. 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]

  3. 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 ...

  4. Computational methods for free surface flow - Wikipedia

    en.wikipedia.org/wiki/Computational_methods_for...

    Position of free surface is corrected to compensate for the non-zero mass flux with the volume flux due to the movement of the each free-surface cell face by enforcing the kinematic boundary conditions. Iterate until no further correction is needed, satisfying the continuity and momentum equations. Advance to the next time step. [1]

    Consider situation solid wall parallel to the x-direction: Assumptions made and relations considered- The near wall flow is considered as laminar and the velocity varies linearly with distance from the wall; No slip condition: u = v = 0. In this we are applying the “wall functions” instead of the mesh points.

    The pressure gradient does not enter into the 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.

  8. Thermal boundary layer thickness and shape - Wikipedia

    en.wikipedia.org/wiki/Thermal_boundary_layer...

    This turbulent boundary layer thickness formula assumes 1) the flow is turbulent right from the start of the boundary layer and 2) the turbulent boundary layer behaves in a geometrically similar manner (i.e. the velocity profiles are geometrically similar along the flow in the x-direction, differing only by stretching factors in and (,) [5 ...

  9. Boundary layer thickness - Wikipedia

    en.wikipedia.org/wiki/Boundary_layer_thickness

    The boundary layer thickness, , is the distance normal to the wall to a point where the flow velocity has essentially reached the 'asymptotic' velocity, .Prior to the development of the Moment Method, the lack of an obvious method of defining the boundary layer thickness led much of the flow community in the later half of the 1900s to adopt the location , denoted as and given by
