Shape factor is also named as view factor or configuration factor. Shape factor depends only on geometry. As radiation is emitting from a body at a high temperature, only some part of the radiation will be falling on the other body. The fall of radiation to this body depends on its orientation to the emitting body.

Convection resistance
noun
es: Resistencia a la convección
Critical radius of insulation
noun
The thickness upto which heat flow increases and after which heat flow decreases is termed as critical thickness. In the case of cylinders and spheres it is called critical radius. It can be derived the critical radius of insulation depends on the thermal conductivity of the insulation k and the external convection heat transfer coefficient h.
es: Radio crítico de aislamiento
Cylinder conduction resistance
noun
es: Resistencia de conducción del cilindro
Efficiency
noun
Efficiency signifies a peak level of performance that uses the least amount of inputs to achieve the highest amount of output. Efficiency requires reducing the number of unnecessary resources used to produce a given output including personal time and energy.
es: Eficiencia
Fin effectiveness
noun
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 (i.e., its material thermal conductivity is infinite).
es: Eficacia de la aleta
Fin efficiency
noun
is the ratio of the heat transferred by a fin to the heat that would have been transferred if the total fin surface were at the base (or wall) temperature.
es: Eficiencia de las aletas
Interface resistance
noun
es: Resistencia de interfaz
Plane wall conduction resistance
noun
es: Resistencia a la conducción de la pared plana
Radiation resistance
noun
es: Resistencia a la radiación
Sphere conduction resistance
noun
Consider heat conduction through a hollow sphere of inner radius r1, outer radius r2 and made of a material of constant thermal conductivity. The inner and outer surfaces are maintained at constant but different temperatures t1 and t2 respectively.
es: Resistencia a la conducción de la esfera
Surfaces
noun
the exterior or upper boundary of an object or body.
es: Superficies
Thermal contact conductance
noun
es: Conductancia de contacto térmico
Thermal contact resistance
noun
When a junction is formed by pressing two similar or dissimilar metallic materials together, only a small fraction of the nominal surface area is actually in contact because of the nonflatness and roughness of the contacting surfaces. If a heat flux is imposed across the junction, the uniform flow of heat is generally restricted to conduction through the contact spots, as shown in Figure 1. The limited number and size of the contact spots results in an actual contact area which is significantly smaller than the apparent contact area. This limited contact area causes a thermal resistance, the contact resistance or thermal contact resistance.
es: Resistencia al contacto térmico
Total thermal resistance
noun
is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow. Thermal resistance is the reciprocal of thermal conductance.
