Thermal neutron reactor

energy

A thermal-neutron reactor is a nuclear reactor that uses slow or thermal neutrons.

Thermal power generation

energy

Heat energy that is converted to electricity. Usually water is heated into steam which is used to drive turbines.

Thermal protective aid

marine

A lightweight waterproof garment intended to conserve body heat and be worn by persons suffering from exposure to cold temperatures, e.g. a person recovered from the sea.

Thermal radiation

energy

Electromagnetic radiation generated by the thermal motion of particles in matter.

Thermal resistivity

energy

Opposite to Thermal conductivity, a meaure of a substance ability to resist heat flow.

Thermal runaway

energy

Thermal runaway describes a process that is accelerated by increased temperature, in turn releasing energy that further increases temperature.

Thermal shielding

energy

Thermal shields protect structures from extreme temperatures and thermal gradients by either thermal insulation or radiative cooling, which respectively isolate the underlying structure from high external surface temperatures, while emitting heat outwards through thermal radiation.

Thermal shock

energy

Thermal shock is a type of rapidly transient mechanical load.

Thermal treatment

energy

Thermal treatment is any waste treatment technology that involves high temperatures in the processing of the waste feedstock.

Thermal trip

marine

A device which is operated by a rise in temperature. It is used on circuit breakers, relays, etc., and is often a bimetallic strip which deflects when heated.

Thermocline

energy

A thermocline is a thin but distinct layer in a large body of fluid in which temperature changes more drastically with depth than it does in the layers above or below. In the ocean, the thermocline divides the upper mixed layer from the calm deep water below.

Thermocouple

energy

A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction.

Thermodynamic cycle

energy

A thermodynamic cycle consists of a linked sequence of thermodynamic processes that involve transfer of heat and work into and out of the system, while varying pressure, temperature, and other state variables within the system, and that eventually returns the system to its initial state.

Thermodynamic equilibrium

energy

Thermodynamic equilibrium is an axiomatic concept of thermodynamics.

Thermodynamic free energy

energy

Free energy is the maximum amount of work that a thermodynamic system can perform in a process at constant temperature, and its sign indicates whether a process is thermodynamically favorable or forbidden.

Thermodynamic operation

energy

A thermodynamic operation is an externally imposed manipulation that affects a thermodynamic system.

Thermodynamic system

energy

A thermodynamic system is a body of matter and/or radiation, confined in space by walls, with defined permeabilities, which separate it from its surroundings.

Thermodynamics

energy

Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, radiation, and physical properties of matter.

Thermoelectric generator

energy

A thermoelectric generator, also called a Seebeck generator, is a solid state device that converts heat flux (temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect (a form of thermoelectric effect).

Thermoelectric materials

energy

Thermoelectric materials show the thermoelectric effect in a strong or convenient form.
