Conduction shape factor
noun
This approach applied to 2-D conduction involving two isothermal surfaces, with all other surfaces being adiabatic. The heat transfer from one surface (at a temperature T1) to the other surface (at T2) can be expressed as: q=Sk(T1-T2) where k is the thermal conductivity of the solid and S is the conduction shape factor.
es: Factor de forma de conducción
Convection resistance
plural noun
the convection resistance per unit area is the inverse of the convection heat transfer coefficient.
es: Resistencia a la convección
Critical radius of insulation
noun
is defined as the outer radius. that provides maximum rate of heat transfer.
es: Radio crítico de aislamiento
Cylinder conduction resistance
plural noun
is the thermal resistance of the cylindrical layer against heat conduction, or simply the conduction resistance of the cylinder layer.
es: Resistencia de conducción del cilindro
Efficiency
noun
the condition or fact of producing the results you want without waste, or a particular way in which this is done
Example: Efficiency index (10.02 points better in the pronutrients batch)
es: Eficiencia
Fin effectiveness
plural noun
The fin temperature effectiveness or fin efficiency is defined as the ratio of the actual heat transfer rate through the fin base divided by the maximum possible heat transfer rate through the fin base, which can be obtained if the entire fin is at base temperature
es: Eficacia de la aleta
Fin efficiency
plural noun
is defined as the ratio of actual heat flow of the fin to that which would be obtained with a fin of constant temperature uniformly equal to the base surface temperature, that is, one with infinite thermal conductivity.
Example: The influence on heat transfer coefficient, fin efficiency and heat flux was found.
es: Eficiencia de las aletas
Interface resistance
noun
also known as thermal boundary resistance, or Kapitza resistance, is a measure of an interface's resistance to thermal flow.
Example: Such a combination also minimizes contact interface resistance and material transfer.
es: Resistencia de interfaz
Plane wall conduction resistance
plural noun
Plane wall conduction resistance
es: Resistencia a la conducción de la pared plana
Radiation resistance
noun
the component of antenna resistance that accounts for the power radiated into space and is equal in ohms to the radiated power in watts divided by the square of the effective current in amperes at the point of power supply
Example: A cross-linked polystyrene copolymer which is rigid, transparent and colorless with outstanding electrical properties, including low dielectric losses up to very high frequencies, and very high radiation resistance.
es: resistencia a la radiación
Sphere conduction resistance
plural noun
Steady state heat transfer through pipes is in the normal direction to the wall surface (no
significant heat transfer occurs in other directions).
es: Resistencia a la conducción de la esfera
Surfaces
noun
the outside part or uppermost layer of something (often used when describing its texture, form, or extent).
Example: Surfaces can become very hot if exposed to direct sunlight.
es: Superficies
Thermal contact conductance
plural noun
This phenomenon is said to be a result of a thermal contact resistance existing between the contacting surfaces.
es: Conductancia de contacto térmico
Thermal contact resistance
plural noun
The thermal contact conductance coefficient, is a property indicating the thermal conductivity, or ability to conduct heat, between two bodies in contact. The inverse of this property is termed thermal contact resistance.
Example: Calculations can include thermal contact resistance.
es: Resistencia al contacto térmico
Total thermal resistance
plural noun
is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow.
Example: When materials are place in series, their thermal resistances are added so that the same area will conduct less energy for a given temperature difference. An example of this is a cavity-brick wall, with two layers of brick, an air gap and 12mm of plasterboard - all in series.
