boundary-layer equation
11Debye-Hückel equation — The Debye Hückel limiting law, named for its developers Peter Debye and Erich Hückel, provides one way to obtain activity coefficients Ref|Harris. Activities, rather than concentrations, are needed in many chemical calculations because solutions… …
12Double layer (interfacial) — A double layer (DL, also called an electrical double layer, EDL) is a structure that appears on the surface of an object when it is placed into a liquid. The object might be a solid particle, a gas bubble, a liquid droplet, or a porous body. The… …
13Grain boundary — A grain boundary is the interface between two grains in a polycrystalline material. Grain boundaries disrupt the motion of dislocations through a material, so reducing crystallite size is a common way to improve strength, as described by the Hall …
14Divergent boundary — In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent… …
15Convergent boundary — In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of lithosphere move toward one another and collide. As …
16Poisson-Boltzmann equation — The Poisson Boltzmann equation is a differential equation that describes electrostatic interactions between molecules in ionic solutions. It is the mathematical base for the Gouy Chapman double layer (interfacial) theory; first proposed by Gouy… …
17POHLHAUSEN — GERMANY (see also List of Individuals) 20.5.1890 Mittwaida/D 18.11.1980 Gainesville FL/USA Karl Pohlhausen was educated as a mathematician at the Universities of Jena and Göttingen, there being attached to Ludwig Prandtl (1875 1953). In 1919,… …
18Turbulent Prandtl number — The turbulent Prandtl number (Pr t) is a non dimensional term defined as the ratio between the momentum eddy diffusivity and the heat transfer eddy diffusivity. It is useful for solving the heat transfer problem of turbulent boundary layer flows …
19уравнение пограничного слоя — Уравнение движения в пограничном слое [А.С.Гольдберг. Англо русский энергетический словарь. 2006 г.] Тематики энергетика в целом EN boundary layer equation …
20fluid mechanics — an applied science dealing with the basic principles of gaseous and liquid matter. Cf. fluid dynamics. [1940 45] * * * Study of the effects of forces and energy on liquids and gases. One branch of the field, hydrostatics, deals with fluids at… …
