Thermal shock — is the name given to cracking as a result of rapid temperature change. Glass and ceramic objects are particularly vulnerable to this form of failure, due to their low toughness, low thermal conductivity, and high thermal expansion coefficients.… … Wikipedia
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 resistance in electronics — Thermal resistance is the temperature difference across a structure when a unit of heat energy flows through it in unit time. It is the reciprocal of thermal conductance. The SI units of thermal resistance are kelvins per watt, or the equivalent… … Wikipedia
Thermal degradation of polymers — is molecular deterioration as a result of overheating. At high temperatures the components of the long chain backbone of the polymer can begin to separate (molecular scission) and react with one another to change the properties of the polymer.… … Wikipedia
Limit state design — (LSD) refers to a design methodology used in structural engineering. The methodology is in fact a modernization and rationalization of engineering knowledge which was well established prior to the adoption of LSD. Beyond the concept of a limit… … Wikipedia
thermal barrier — n. a limit to the speed of flight of vehicles in the atmosphere set by the effects of aerodynamic heating … English World dictionary
thermal barrier — noun a limit to high speed flight imposed by aerodynamic heating • Syn: ↑heat barrier • Hypernyms: ↑limit, ↑bound, ↑boundary * * * noun : a limit to unlimited increase in airplane or rocket speeds imposed by aerodynamic heating that without… … Useful english dictionary
Thermal copper pillar bump — The Thermal Copper Pillar Bump, also known as the thermal bump , is a thermoelectric device made from thin film thermoelectric material embedded in flip chip interconnects (in particular copper pillar solder bumps) for use in electronics and… … Wikipedia
Thermal power station — Republika Power Plant, a thermal power station in Pernik, Bulgaria … Wikipedia
Thermal efficiency — In thermodynamics, the thermal efficiency (eta {th} ,) is a dimensionless performance measure of a thermal device such as an internal combustion engine, a boiler, or a furnace, for example. The input, Q {in} ,, to the device is heat, or the heat… … Wikipedia
