Reynolds number — In fluid mechanics and heat transfer, the Reynolds number mathrm{Re} is a dimensionless number that gives a measure of the ratio of inertial forces ({old mathrm V} ho) to viscous forces (mu / L) and, consequently, it quantifies the relative… … Wikipedia
Magnetic Reynolds number — The Magnetic Reynolds number is a dimensionless group that occurs in magnetohydrodynamics. It gives an estimate of the effects of magnetic advection to magnetic diffusion, and is typically defined by: where U is a typical velocity scale of the… … Wikipedia
magnetic Reynolds number — ▪ physics combination of quantities that indicates the dynamic behaviour of a plasma. This number is analogous to the Reynolds number of ordinary fluid mechanics, which is used to determine whether or not a fluid flow will smooth out or… … Universalium
Dynamic similarity (Reynolds and Womersley numbers) — Contents 1 Derivation 2 Dynamic similarity use 3 Boundary layer thickness 4 References 5 Exter … Wikipedia
Nusselt number — In heat transfer at a boundary (surface) within a fluid, the Nusselt number is the ratio of convective to conductive heat transfer across (normal to) the boundary. Named after Wilhelm Nusselt, it is a dimensionless number. The conductive… … Wikipedia
Air flow bench — An air flow bench is a device used for testing the internal aerodynamic qualities of an engine component and is related to the more familiar wind tunnel. Used primarily for testing the intake and exhaust ports of cylinder heads of internal… … Wikipedia
Womersley number — A Womersley number is a dimensionless number in biofluid mechanics. It is a dimensionless expression of the of pulsatile flow frequency in relation to viscous effects. It is named after John R. Womersley (1907 1958).The Womersley number, usually… … Wikipedia
Péclet number — In fluid dynamics, the Péclet number is a dimensionless number relating the rate of advection of a flow to its rate of diffusion, often thermal diffusion. It is equivalent to the product of the Reynolds number with the Prandtl number in the case… … Wikipedia
Stokes flow — An object moving through a gas or liquid experiences a force in direction opposite to its motion. Terminal velocity is achieved when the drag force is equal in magnitude but opposite in direction to the force propelling the object. Shown is a… … Wikipedia
Strouhal number — In dimensional analysis, the Strouhal number is a dimensionless number describing oscillating flow mechanisms. Often, it is given as:: mathrm{Sr}= {f Lover v} where Sr is the dimensionless Strouhal number, f is the frequency of vortex shedding, L … Wikipedia
Inviscid flow — In fluid dynamics there are problems that are easily solved by using the simplifying assumption of an ideal fluid that has no viscosity. The flow of a fluid that is assumed to have no viscosity is called inviscid flow. [Clancy, L.J., Aerodynamics … Wikipedia
