  2. Navier–Stokes equations - Wikipedia

    en.wikipedia.org/wiki/NavierStokes_equations

    The incompressible NavierStokes equation is a differential algebraic equation, having the inconvenient feature that there is no explicit mechanism for advancing the pressure in time. Consequently, much effort has been expended to eliminate the pressure from all or part of the computational process.

    The streamline upwind Petrov–Galerkin pressure-stabilizing Petrov–Galerkin formulation for incompressible NavierStokes equations can be used for finite element computations of high Reynolds number incompressible flow using equal order of finite element space (i.e. ) by introducing additional stabilization terms in the NavierStokes Galerkin formulation.

  4. Pressure-correction method - Wikipedia

    en.wikipedia.org/wiki/Pressure-correction_method

    Pressure-correction method is a class of methods used in computational fluid dynamics for numerically solving the Navier-Stokes equations normally for incompressible flows. Common properties [ edit ]

    en.wikipedia.org/wiki/Non-dimensionalization_and...

    In fluid mechanics, non-dimensionalization of the NavierStokes equations is the conversion of the NavierStokes equation to a nondimensional form. This technique can ease the analysis of the problem at hand, and reduce the number of free parameters. Small or large sizes of certain dimensionless parameters indicate the importance of certain ...

    en.wikipedia.org/wiki/Large_eddy_simulation

    Large eddy simulation of a turbulent gas velocity field.. Large eddy simulation (LES) is a mathematical model for turbulence used in computational fluid dynamics.It was initially proposed in 1963 by Joseph Smagorinsky to simulate atmospheric air currents, [1] and first explored by Deardorff (1970). [2]

    en.wikipedia.org/wiki/Projection_method_(fluid...

    In computational fluid dynamics, the projection method, also called Chorin's projection method, is an effective means of numerically solving time-dependent incompressible fluid-flow problems. It was originally introduced by Alexandre Chorin in 1967 [1] [2] as an efficient means of solving the incompressible Navier-Stokes equations.

  8. Landau–Squire jet - Wikipedia

    en.wikipedia.org/wiki/Landau–Squire_jet

    This is an exact solution to the incompressible form of the Navier-Stokes equations, which was first discovered by Lev Landau in 1944 [1] [2] and later by Herbert Squire in 1951. [3] The self-similar equation was in fact first derived by N. A. Slezkin in 1934, [ 4 ] but never applied to the jet.

  9. Derivation of the Navier–Stokes equations - Wikipedia

    en.wikipedia.org/wiki/Derivation_of_the_Navier...

    In the analysis of a flow, it is often desirable to reduce the number of equations and/or the number of variables. The incompressible NavierStokes equation with mass continuity (four equations in four unknowns) can be reduced to a single equation with a single dependent variable in 2D, or one vector equation in 3D.
