Incompressibility information

Incompressibility may refer to: a property in thermodynamics and fluid dynamics, see Compressibility or Incompressible flow a property of a vector field...

required for incompressible flow is that the divergence of the flow velocity vanishes. In some fields, a measure of the incompressibility of a flow is...

Since this notion of incompressibility for a sphere is quite different from the above definition for surfaces, often an incompressible sphere is instead...

by only a few bits (are incompressible). The incompressibility method depends on an objective, fixed notion of incompressibility. Such a notion was provided...

An incompressible string is a string with Kolmogorov complexity equal to its length, so that it has no shorter encodings. The pigeonhole principle can...

essential laminations in 3-manifolds. He invented the notion of "end-incompressibility" and several of his students, such as Mark Brittenham, Charles Delman...

the speed of sound. The Mach number is used to evaluate whether the incompressibility can be assumed, otherwise the effects of compressibility must be included...

incompressible (divergence-free), two-dimensional flows. The Stokes stream function, named after George Gabriel Stokes, is defined for incompressible...

\,\!\alpha _{p}} are material constants. Under the assumption of incompressibility one can rewrite as W ( λ 1 , λ 2 ) = ∑ p = 1 N μ p α p ( λ 1 α p +...

providing much lower forces due to the incompressibility. The hydraulic working fluid is practically incompressible, leading to a minimum of spring action...

can be thought of as the fluid's kinetic energy per unit volume. For incompressible flow, the dynamic pressure of a fluid is the difference between its...

process (285.8 kJ/mol, or 15.9 MJ/kg). Liquid water can be assumed to be incompressible for most purposes: its compressibility ranges from 4.4 to 5.1×10−10 Pa−1...

this method's purpose is to minimize infiltration of surface water and incompressible material into the joint system. Joint sealants are also used to reduce...

modelled as an incompressible flow. Otherwise the more general compressible flow equations must be used. Mathematically, incompressibility is expressed...

readily available, buoyant, and, for all practical purposes, incompressible. The incompressibility of the gasoline means the tanks can be very lightly constructed...

does not depend on the velocity or stress state of the fluid. For an incompressible and isotropic Newtonian fluid in laminar flow only in the direction...

may be defined geometrically, as an embedded, non-boundary parallel, incompressible torus, or it may be defined algebraically, as a subgroup Z × Z {\displaystyle...

determine the approximation with which a flow can be treated as an incompressible flow. The medium can be a gas or a liquid. The boundary can be travelling...

describe the force balance at a given point within a fluid. For an incompressible fluid with vector velocity field u {\displaystyle \mathbf {u} } , the...

irrotational. The automatic condition ∂2Ψ/∂x ∂y = ∂2Ψ/∂y ∂x then gives the incompressibility constraint ∇ · v = 0. Any differentiable function may be used for...

when the head is submerged underwater. This is because the relative incompressibility of a liquid presents resistance to the force of the sound waves traveling...
