Critical heat flux — describes the thermal limit of a phenomenon where a phase change occurs during heating (such as bubbles forming on a metal surface used to heat water), which suddenly decreases the efficiency of heat transfer, thus causing localised overheating… … Wikipedia
Heat transfer — is a discipline of thermal engineering that concerns the exchange of thermal energy from one physical system to another. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and phase change … Wikipedia
Heat flux — or thermal flux is a flow of energy per unit of area per unit of time. In SI units, it is measured in [W·m 2] . It has both a direction and a magnitude so it is a vectorial quantity. To define the heat flux at a certain point in space, one takes… … Wikipedia
Rayleigh flow — refers to diabatic flow through a constant area duct where the effect of heat addition or rejection is considered. Compressibility effects often come into consideration, although the Rayleigh flow model certainly also applies to incompressible… … Wikipedia
Geothermal heat pump — A geothermal heat pump system is a heating and/or an air conditioning system that uses the Earth s ability to store heat in the ground and water thermal masses. These systems operate based on the stability of underground temperatures: the ground… … Wikipedia
Choked flow — is a compressible flow effect. The parameter that becomes choked or limited is the velocity or the mass flow rate. Choked flow is a fluid dynamic condition associated with the Venturi effect. When a flowing fluid at a given pressure and… … Wikipedia
Renewable heat — is an application of renewable energy. It refers to the renewable generation of heat, rather than electrical power.Many colder countries consume more energy for heating than electrical power. For example, in 2005 the United Kingdom consumed 354… … Wikipedia
Mass flow sensor — A mass airflow sensor. A mass air flow sensor is used to find out the mass flowrate of air entering a fuel injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the… … Wikipedia
