Thermal insulation is the reduction of heat transfer (the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence.
Burn
A burn is a type of injury to skin, or other tissues, caused by heat, cold, electricity, chemicals, friction, or radiation.
Thermal mass
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.
Hypothermia
Hypothermia is defined as a body core temperature below 35.
Black body
A black body is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence.
Heat
In physics, heat is energy that spontaneously passes between a system and its surroundings in some way other than through work or the transfer of matter.
Calorimetry
Calorimetry is the science or act of measuring changes in state variables of a body for the purpose of deriving the heat transfer associated with changes of its state due for example to chemical reactions, physical changes, or phase transitions under specified constraints.
Heat sink
A heat sink (also commonly spelled heatsink) is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature at optimal levels.
Thermal radiation
Thermal radiation is electromagnetic radiation generated by the thermal motion of charged particles in matter.
Heat pipe
A heat pipe is a heat-transfer device that combines the principles of both thermal conductivity and phase transition to efficiently manage the transfer of heat between two solid interfaces.
Condenser (heat transfer)
Other Types of Condensers In the world of Heating, Ventilation, and Air Conditioning (HVAC), condensers happen to be a topic of great importance.
Convective heat transfer
Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids.
Thermal energy storage
Thermal energy storage (TES) is achieved with greatly differing technologies that collectively accommodate a wide range of needs.
Efficiency
Efficiency is the (often measurable) ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result.
Heat transfer physics
Heat transfer physics describes the kinetics of energy storage, transport, and transformation by principal energy carriers: phonons (lattice vibration waves), electrons, fluid particles, and photons.
Heat transfer coefficient
The heat transfer coefficient or film coefficient, or film effectiveness, in thermodynamics and in mechanics is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat (i.e., the temperature difference, ΔT): where: q: amount of heat transferred (heat flux), W/m2 i.
Thermal conduction
Thermal conduction is the transfer of heat (internal energy) by microscopic collisions of particles and movement of electrons within a body.
Boiling
Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.
Rolf Heinrich Sabersky
Rolf Heinrich Sabersky (born 20 October 1920) professor emeritus in mechanical engineering at Caltech.
Waste heat
Waste heat is by necessity produced both by machines that do work and in other processes that use energy, for example in a refrigerator warming the room air or a combustion engine releasing heat into the environment.
Stefan–Boltzmann law
The Stefan–Boltzmann law describes the power radiated from a black body in terms of its temperature.
Black-body radiation
Black-body radiation is the type of electromagnetic radiation within or surrounding a body in thermodynamic equilibrium with its environment, or emitted by a black body (an opaque and non-reflective body), assumed for the sake of calculations and theory to be held at constant, uniform temperature.
Natural convection
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 temperature gradients.
R-value (insulation)
The R-value is a measure of thermal resistance for materials and assemblies of materials (such as insulation panels, floors, and walls) in the building and construction industry.
Applied Thermal Engineering
Applied Thermal Engineering is a peer-reviewed scientific journal publishing original articles concerning all aspects of the thermal engineering of advanced processes, including process integration, intensification, and development, together with the application of thermal equipment in conventional process plant, which includes its use for heat recovery.
