however, the anode is still the part receiving the largest heat flux.

The total heat flux from the porous plug into the plug holder is thereby Af.

Detailed studies of evaporation involve boundary layer considerations as well as momentum, heat flux and energy budgets.

Liquid sodium is used as a heat transfer fluid in some fast reactors, due to its high thermal conductivity and low neutron absorption cross section, which is required to achieve a high neutron flux ; the high boiling point allows the reactor to operate at ambient pressure.

When the iron tip oxidises and burnt flux accumulates on it, solder no longer wets the tip, impeding heat transfer and making soldering difficult or impossible ; tips must be periodically cleaned in use.

However, any leakage flux that intercepts nearby conductive materials such as the transformer's support structure will give rise to eddy currents and be converted to heat.

His concept was to put some tritium and / or deuterium in close proximity to a fission bomb, with the hope that the heat and intense flux of neutrons released when the bomb exploded, would ignite a self sustaining fusion reaction.

In transport phenomena ( heat transfer, mass transfer and fluid dynamics ), flux is defined as the rate of flow of a property per unit area, which has the dimensions ·< sup >− 1 </ sup >·< sup >− 1 </ sup >.

# Heat flux, the rate of heat flow across a unit area ( J · m < sup >− 2 </ sup >· s < sup >− 1 </ sup >).

( Fourier's law of conduction ) ( This definition of heat flux fits Maxwell's original definition.

Also acts as a generalization of heat flux, which is equal to the radiative flux when restricted to the infrared spectrum.

The radiative flux and heat flux are specific cases of energy flux.

* Latent heat flux

Constant flux calorimetry ( or COFLUX as it is often termed ) is derived from heat balance calorimetry and uses specialized control mechanisms to maintain a constant heat flow ( or flux ) across the vessel wall.

Thermoelectric cooling uses the Peltier effect to create a heat flux between the junction of two different types of materials.

Amalthea radiates slightly more heat than it receives from the Sun, which is probably due to the influence of Jovian heat flux (< 9 kelvins ), sunlight reflected from the planet (< 5 K ), and charged particle bombardment (< 2 K ).

In a differential scanning calorimeter ( DSC ), heat flow into a sample — usually contained in a small aluminium capsule or ' pan '— is measured differentially, i. e., by comparing it to the flow into an empty reference pan.

Differential scanning calorimetry or DSC is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature.

The term DSC was coined to describe this instrument which measures energy directly and allows precise measurements of heat capacity.

DSC measures the energy required to keep both the reference and the sample at the same temperature whereas DTA measures the difference in temperature between the sample and the reference when they are both put under the same heat.

The result of a DSC experiment is a curve of heat flux versus temperature or versus time.

* Differential scanning calorimetry ( DSC ): heat difference

DSC is used to determine the curing properties of the resins used in composite materials, and can also confirm whether a resin can be cured and how much heat is evolved during that process.

Simultaneous TGA-DTA / DSC measures both heat flow and weight changes ( TGA ) in a material as a function of temperature or time in a controlled atmosphere.

Sear on both sides then cover meat loosely with heat reflecting foil for juiciest results.

It would appear that it should be possible to determine unique mechanisms for the thermal and photochemical reactions in both the liquid and gas phases and to determine values for activation energies of some of the intermediate reactions of atoms and free radicals, as well as information on the heat of dissociation of the carbon-halogen bond.

He explained that though both sun and the stars were fiery stones, we do not feel the heat of the stars because of their enormous distance from earth.

In transition regions, where this pressure dependent dissociation is incomplete, both the differential, constant pressure heat capacity and beta ( the volume / pressure differential ratio ) will greatly increase.

Humanure kills these pathogens both by the extreme heat of the composting and the extended amount of time ( 1 to 2 years ) that it is allowed to decompose.

It is not really fire, for fire is an excess of heat and a sort of ebullition ; but in reality, of what we call air, the part surrounding the earth is moist and warm, because it contains both vapour and a dry exhalation from the earth.

However, both numbers would be a fraction of the heat generated by many high performance processors, some years later.

A strong vacuum inside the bulb does not permit motion, because there are not enough air molecules to cause the air currents that propel the vanes and transfer heat to the outside before both sides of each vane reach thermal equilibrium by heat conduction through the vane material.

: This term is used both for conventional p – n diodes used to monitor temperature due to their varying forward voltage with temperature, and for Peltier heat pumps for thermoelectric heating and cooling .. Peltier heat pumps may be made from semiconductor, though they do not have any rectifying junctions, they use the differing behaviour of charge carriers in N and P type semiconductor to move heat.

When both were prepared for flight, Daedalus warned Icarus not to fly too high, because the heat of the sun would melt the wax, nor too low, because the sea foam would soak the feathers.

The Otto cycle by comparison has both the heat addition and rejection at constant volume.

These interactions produce either electric currents or heat, or both.

Transfer of thermal energy by heat occurs by both of these mechanisms: heat can be transferred by electromagnetic radiation, or by physical contact in which direct particle-particle impacts transfer kinetic energy.

An explosion is a type of spontaneous chemical reaction that, once initiated, is driven by both a large exothermic change ( great release of heat ) and a large positive entropy change ( great quantities of gases are released ) in going from reactants to products, thereby constituting a thermodynamically favorable process in addition to one that propagates very rapidly.

A considerable portion of all sapphire and ruby is treated with a variety of heat treatments to improve both color and clarity.

However, endothermic homeotherms ( the animals generally characterized as " warm-blooded ") both produce more heat and have better ways to retain and regulate it than other animals.

HCCI type engines take in both air and fuel, but continue to rely on an unaided auto-combustion process, due to higher pressures and heat.

With both methods, after shaping, the steel must be heat treated.

A metal ( from Greek " μέταλλον " – métallon, " mine, quarry, metal ") is an element, compound, or alloy that is a good conductor of both electricity and heat.

A CPU socket provides many functions, including a physical structure to support the CPU, support for a heat sink, facilitating replacement ( as well as reducing cost ), and most importantly, forming an electrical interface both with the CPU and the PCB.

Frictional heat and sparks generated by mining equipment can ignite both methane gas and coal dust explosions.
