The therm is a non-SI unit of heat energy equal to 100000 British thermal units (Btu).
A device used to store and release thermal energy.
Thermal breeder reactor which use thermal-spectrum (i.e.: moderated) neutrons to breed fissile uranium-233 from thorium (thorium fuel cycle).
The amount of heat given to a material to make a unit change in temperature in that material.
Thermal coal is coalthat is burnt as a solid fuel in coal power stations to generate electricity.
Thermal comfort is the condition of mind that expresses satisfaction with the thermal environment and is assessed by subjective evaluation.
The transfer of internal energy by microscopic collisions of particles and movement of electrons within a body. Conduction takes place in all phases: solid, liquid, and gas.
A measure of a substances ability to conduct heat.
Convection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid.
The ratio of the work done by an engine to the mechanical equivalent of the heat available in fuel.
In thermodynamics, the thermal effusivity, thermal inertia or thermal responsivity of a material is defined as the square root of the product of the material's thermal conductivity and its volumetric heat capacity.
Thermal energy is the energy that determines the temperature of matter.
Generated thermal energy can be stored in thermal storage tanks, also known as heat storage tanks, in order to decouple heat production from electricity production.
A thermal energy storage tank is a naturally stratified thermal accumulator that allows the storage of chilled water produced during off-peak time, to use this energy later during on-peak time to chill steam turbine inlet air and increment its power output.
Thermal engineering is a specialized sub-discipline of mechanical engineering that deals with the movement of heat energy and transfer.
Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions.
Thermal hydraulics (also called thermohydraulics) is the study of hydraulic flow in thermal fluids.
Thermal insulation is the reduction of heat transfer between objects in thermal contact or in range of radiative influence.
In building design, thermal mass is a property of the mass of a building which enables it to store heat, providing "inertia" against temperature fluctuations.
A thermal neutron is a free neutron with a kinetic energy of about 0.025 eV (about 4.0×10−21 J or 2.4 MJ/kg, hence a speed of 2.19 km/s), which is the most probable energy at a temperature of 290 K (17 °C or 62 °F).
