the act of laying claim to or taking possession of something

Boundary conditions
Noun
a condition which a quantity that varies throughout a given space or enclosure must fulfill at every point on the boundary of that space especially when the velocity of a fluid at any point on the wall of a rigid conduit is necessarily parallel to the wall
es: Condiciones de borde
Emissivity
Noun
the relative power of a surface to emit heat by radiation : the ratio of the radiant energy emitted by a surface to that emitted by a blackbody at the same temperature
es: Emisividad
Energy balance
Noun
he relation between intake of food and output of work (as in muscular or secretory activity) that is positive when the body stores extra food as fats and negative when the body draws on stored fat to provide energy for work
es: Balance de energía
Heat Conduction Equation
Conjunction
The heat conduction equation is a partial differential equation that describes the distribution of heat (or the temperature field) in a given body over time. Detailed knowledge of the temperature field is very important in thermal conduction through materials.
es: Ecuación de conducción de calor
Heat flux
Conjunction
Heat flux or thermal flux, sometimes also known as heat flux density or heat flow rate intensity is a flux of energy per unit area per unit time. In SI, its units are watts per square meter.
es: Flujo de calor
Insulation
Noun
The concept of thermal insulation is associated with the concept of controllability of heat transmission when it is desired that it does not exceed certain limits. A thermal insulating product is a product that reduces the transmission of heat through the structure on which, or in which it is installed. Numeric limits can only be defined when the specific application has been defined.
es: Aislamiento
Internal energy
Noun
the total amount of kinetic and potential energy possessed by the molecules of a body and their ultimate parts owing to their relative positions and their motions inside the body and excluding the energy due to the passage of waves through the body and to vibrations of the body
es: Energía interna
Thermal conductivity
Noun
the quantity of heat that passes in unit time through a unit area of plate whose thickness is unity when its opposite faces differ in temperature by one degree
es: Conductividad térmica
Thermal diffusivity
Noun
Thermal diffusivity, in heat transfer problems, is the value obtained by dividing the thermal conductivity of a certain material divided by the product of its density value and its specific heat capacity.
es: Difusividad térmica
Thermal symmetry
Conjunction
A special case of this condition corresponds to the perfectly isolated surface for which (∂T / ∂x = 0). Heat transfer through a properly insulated surface can be considered zero, as proper insulation reduces heat transfer across a surface to negligible levels.
