thermal diffusivity coefficient
1Thermal conductivity — In physics, thermal conductivity, k, is the property of a material that indicates its ability to conduct heat. It appears primarily in Fourier s Law for heat conduction.First, we define heat conduction by the formula::: H=frac{Delta Q}{Delta t}=k …
2Thermal oxidation — In microfabrication, thermal oxidation is a way to produce a thin layer of oxide (usually silicon dioxide) on the surface of a wafer (semiconductor). The technique forces an oxidizing agent to diffuse into the wafer at high temperature and react… …
3Alpha — may refer to:The Greek letter alphaAlpha (letter), a letter in the Greek alphabet. α may be used as the symbol for: *Alpha channel, describing transparency and opacity in computer graphics *Angle of attack in aerodynamics *Common base current… …
4Natural convection — Bénard cells. Natural convection is a mechanism, or type of heat transport, in which the fluid motion is not generated by any external source (like a pump, fan, suction device, etc.) but only by density differences in the fluid occurring due to… …
5radiation — radiational, adj. /ray dee ay sheuhn/, n. 1. Physics. a. the process in which energy is emitted as particles or waves. b. the complete process in which energy is emitted by one body, transmitted through an intervening medium or space, and… …
6Dimensionless quantity — In dimensional analysis, a dimensionless quantity or quantity of dimension one is a quantity without an associated physical dimension. It is thus a pure number, and as such always has a dimension of 1.[1] Dimensionless quantities are widely used… …
7Greek letters used in mathematics, science, and engineering — Greek alphabet Αα Alpha Νν Nu Ββ Beta …
8fluid 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… …
9Rayleigh number — In fluid mechanics, the Rayleigh number for a fluid is a dimensionless number associated with buoyancy driven flow (also known as free convection or natural convection). When the Rayleigh number is below the critical value for that fluid, heat… …
10Time-Domain Thermoreflectance — is a method by which the thermal properties of a material can be measured, most importantly thermal conductivity. This method can be applied most notably to thin film materials (up to hundreds of nanometers thick), which have properties that vary …
