large heat flux vs Great thermal density

Both phrases are correct, but they convey different meanings. 'Large heat flux' refers to the rate of heat transfer per unit area, while 'great thermal density' refers to the amount of heat energy stored per unit volume. They are not directly comparable as they represent different aspects of heat-related properties.

large heat flux

This phrase is correct and commonly used in English.

This phrase is used to describe a high rate of heat transfer per unit area.

Examples:

  • The large heat flux from the sun warms the Earth's surface.
  • The electronic device generates a large heat flux during operation.
  • Place the heat flux meter in the apparatus in the specimen position so that the target of the heat flux meter is located centrally within the radiator surface.
  • Test method: ISO 5660 in oxidative pyrolysis conditions (IEC 60695-7-1 fire type 1b with a heat flux of 50 kW/m2).
  • For calibration of the radiator, a heat flux meter (radiometer) of the Gardon (foil) type with a design range not exceeding 10 W/cm² shall be used.
  • Constituent materials and other components suitable for protection against radiant and convective heat must possess an appropriate coefficient of transmission of incident heat flux and be sufficiently incombustible to preclude any risk of spontaneous ignition under the foreseeable conditions of use.
  • We got a large heat-and-light anomaly consistent with an explosion.
  • The calibration of the heat flux meter shall be checked whenever a recalibration of the radiator is carried out, by comparison with an instrument held as a reference standard and not used for any other purpose.
  • U.A.V.'s picking up a large heat signature About 23 miles north of your whiskey.
  • Where the outside of these materials and components must be reflective, its reflective power must be appropriate to the intensity of the heat flux due to radiation in the infra-red range.
  • Test method: IEC 60754-1 or ISO 19700 in under-ventilated conditions (IEC 60695-7-1 fire type 3a with a heat flux of 50 kW/m2)
  • Large heating appliances (e.g. large heat blowers, electric stoves, systems for heating marble and natural stone and other large appliances for heating rooms, beds and seating furniture)

Alternatives:

  • high heat flux
  • intense heat transfer
  • significant heat flow
  • substantial thermal transfer
  • considerable heat exchange

Great thermal density

This phrase is correct but less commonly used in English.

This phrase refers to a high amount of heat energy stored per unit volume.

Examples:

  • The material has a great thermal density, allowing it to retain heat for a long time.
  • The liquid has a great thermal density due to its high specific heat capacity.
  • Bill Gross has several companies, including one called eSolar that has some great solar thermal technologies.
  • White phosphorus is a chemical normally used to illuminate enemy positions because, when it explodes, it produces a great flash of thermal energy and anyone exposed to it is totally consumed or suffers irreversible burns to the skin.
  • He won't survive in molecular density is too great.
  • Strong, supple, great bud density.
  • There's a great deal of variation in pattern complexity, quantum density...
  • We have a great density of institutional relations - we have touched on some of them in the debate already.
  • She might have a "great sense of density" for this nation, but that's not the line we want to push.
  • In Seoul's case... because of the city's high population density and many high-rise buildings... the damage can be great.
  • ALs(E) and ALs(B) are derived from the SAR or power density ELVs (Tables A1 and A3) based on the thresholds related to internal thermal effects caused by exposure to (external) electric and magnetic fields.
  • White expandable polystyrene beads with a thermal conductivity of not more than 0,034 W/mK at a density of 14,0 kg/m3 (± 1,5 kg/m3), containing 50 % recycled material
  • relative density at 23 ºC after thermal conditioning for one hour at 100 ºC >= 0,940, in accordance with ISO Standard 1183,
  • I was thinking we were looking at the remains of a burned body, another one of Renton's victims, but the degree of thermal destruction was so great that it would take a significant amount of heat.
  • It would wipe out the east coast essentially through a combination of tsunamis, blast waves, thermal effects, and it would also throw out huge amounts of ejecta that would spread to great distances, igniting additional forest fires.
  • I attach great importance to the method for calculating optimal cost and specifying minimum economic efficiency requirements for the structural components of a building's thermal insulation and services, as well as the application of these calculations both to new and existing buildings.
  • The type of thermal product that is conveyed through the thermal pipe.
  • The force becomes greater and greater, and as matter and energy are compressed to a point, the density is so great that it has no recourse but to rapidly expand outwards again...
  • This will allow for higher areal density.
  • Commander Crichton, she is initiating a thermal increase.
  • Increase thermal input coefficient to 150 percent.
  • Our satellite picked up two thermal images.

Alternatives:

  • high thermal density
  • significant heat capacity
  • substantial thermal mass
  • considerable heat storage
  • intense thermal energy
