Thermal runaway — refers to a situation where an increase in temperature changes the conditions in a way that causes a further increase in temperature leading to a destructive result. It is a kind of positive feedback.Chemical engineeringIn chemical engineering,… … Wikipedia
Thermal barrier coating — Thermal barrier coatings are highly advanced material systems applied to metallic surfaces, such as gas turbine or aero engine parts, operating at elevated temperatures. These coatings serve to insulate metallic components from large and… … Wikipedia
Thermal spraying — techniques are coating processes in which melted (or heated) materials are sprayed onto a surface. The feedstock (coating precursor) is heated by electrical (plasma or arc) or chemical means (combustion flame). Thermal spraying can provide thick… … Wikipedia
Thermal conduction — In heat transfer, conduction (or heat conduction) is a mode of transfer of energy within and between bodies of matter, due to a temperature gradient. Conduction means collisional and diffusive transfer of kinetic energy of particles of ponderable … Wikipedia
Thermal insulation — The term thermal insulation can refer to materials used to reduce the rate of heat transfer, or the methods and processes used to reduce heat transfer.Heat energy can be transferred by conduction, convection, radiation or when undergoing a phase… … Wikipedia
Thermal management of electronic devices and systems — Heat generated by electronic devices and circuitry must be dissipated to improve reliability and prevent premature failure. Techniques for heat dissipation can include heatsinks and fans for air cooling, and other forms of computer cooling such… … Wikipedia
Thermal Hall effect — The thermal Hall effect is the thermal analog of the Hall effect. Here, a thermal gradient is produced across a solid instead of an electric field. When a magnetic field is applied, an orthogonal temperature gradient develops. For conductors, a… … Wikipedia
Thermal 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… … Wikipedia
Thermal equator — The thermal equator (also known as the heat equator ) is a belt encircling the Earth, defined by the set of locations having the highest mean annual temperature at each longitude around the globe. Because local temperatures are sensitive to the… … Wikipedia
thermal turbulence — noun atmospheric turbulence due to convection currents … Wiktionary
thermal updraft — A rising air current in a large thunderstorm that is buoyant because its temperature is warm compared with the surrounding air. “Thermals” are not always associated with thunderstorms; they are useful to soaring pilots and hang gliders, as the… … Aviation dictionary
