91Vorticity equation — The vorticity equation is an important prognostic equation in the atmospheric sciences. Vorticity is a vector, therefore, there are three components. The equation of vorticity (three components in the canonical form) describes the total… …
92Boundary layer — For the anatomical structure, see Boundary layer of uterus. Boundary layer visualization, showing transition from laminar to turbulent condition In physics and fluid mechanics, a boundary layer is that layer of fluid in the immediate vicinity of… …
93Pressure coefficient — The pressure coefficient is a dimensionless number which describes the relative pressures throughout a flow field in fluid dynamics. The pressure coefficient is used in aerodynamics and hydrodynamics. Every point in a fluid flow field has its own …
94Groundwater flow equation — Used in hydrogeology, the groundwater flow equation is the mathematical relationship which is used to describe the flow of groundwater through an aquifer. The transient flow of groundwater is described by a form of the diffusion equation, similar …
95Algorithmically random sequence — Intuitively, an algorithmically random sequence (or random sequence) is an infinite sequence of binary digits that appears random to any algorithm. The definition applies equally well to sequences on any finite set of characters. Random sequences …
96Hyperelastic material — A hyperelastic or Green elastic material is an ideally elastic material for which the stress strain relationship derives from a strain energy density function. The hyperelastic material is a special case of a Cauchy elastic material. For many… …
97Dynamic pressure — In incompressible fluid dynamics dynamic pressure (indicated with q, or Q, and sometimes called velocity pressure) is the quantity defined by:[1] where (using SI units): = dynamic pressure in pascals …
98Ogden (hyperelastic model) — The Ogden material model is a hyperelastic material model used to describe the non linear stress strain behaviour of complex materials such as rubbers, polymers, and biological tissue. The model was developed by Ray W. Ogden in 1972.[1] The Ogden …
99Taylor-Green vortex — In fluid dynamics, the Taylor Green vortex is a 2 dimensional, unsteady flow of a decaying vortex, which has the exact closed form solution of incompressible Navier Stokes equations in Cartesian coordinates. It is named after the British… …
100Stokes stream function — In fluid dynamics, the Stokes stream function is used to describe the streamlines and flow velocity in a three dimensional incompressible flow with axisymmetry. A surface with a constant value of the Stokes stream function encloses a streamtube,… …
