15 Modulo de transferencia de calor e Inglés terms terms
Get acquainted with the subject.
boundary conditions
plural noun
a condition that is required to be satisfied at all or part of the boundary of a region in which a set of differential equations is to be solved.
Example: This type of boundary conditions locks all degrees of freedom for the selected object.
es: condiciones de borde
Emissivity
noun
is the relative power of a surface to emit heat by radiation
Example: Emissivity of all materials does not change equally at different wavelengths.
es: Emisividad
energy balance
noun clause
the relationship between incoming solar radiation, outgoing radiation of all types, and global temperature change.
es: balance de energía
heat conduction equation
noun clause
is a partial differential equation that describes the distribution of heat (or the temperature field) in a given body over time.
es: ecuación de conducción de calor
heat flux
plural noun
sometimes also referred to as heat flux density, heat-flow density or heat flow rate intensity is a flow of energy per unit of area per unit of time. In SI its units are watts per square metre (W/m2).
Example: The convective heat flux reaches 20 MW.m-2 and the attendant surface temperature more than 3000°C.
es: flujo de calor
insulation
noun
creating a barrier between the hot and the cold object that reduces heat transfer by either reflecting thermal radiation or decreasing thermal conduction and convection from one object to the other.
Example: It slows the flow of cold air and adds insulation.
es: aislamiento
internal energy
plural noun
The internal energy of a thermodynamic system is the energy contained within it. It is the energy necessary to create or prepare the system in any given internal state.
Example: They are also used for internal energy transfer during superheating or supercooling of the refrigerant.
es: energía interna
outer
adjective
outside; external.
Example: the outer hall at the museum's main entrance
es: Externo
steady
adjective
firmly fixed, supported, or balanced; not shaking or moving.
Example: the lighter the camera, the harder it is to hold steady
es: firme
surrounding
adjective
all around a particular place or thing.
Example: Nashville and the surrounding area
es: circundante
thermal conductivity
noun clause
Thermal conductivity can be defined as the rate at which heat is transferred by conduction through a unit cross-section area of a material, when a temperature gradient exits perpendicular to the area.
Example: flow rate (M) increases with a lower temperature. THERMAL+CONDUCTIVITY changes with temperature.
es: conductividad térmica
thermal diffusivity
plural noun
is the thermal conductivity divided by density and specific heat capacity at constant pressure.
Example: is the thermal conductivity divided by density and specific heat capacity at constant pressure.
thermal symmetry
plural noun
A heat transfer problem that is symmetric about a plane, line, or point is said to have thermal symmetry about that plane, line, or point. The thermal symmetry boundary condition is a mathematical expression of this thermal symmetry.
Example: By means of the rupture of the thermal symmetry, the living beings were not more abiotic particles squeezed together inside small globules that we call microspheres, which lacked rotational variance and were indistinguishable one from the other.
es: simetría térmica
thickness
noun
the distance between opposite sides of something.
Example: The crystal has a thickness of 8 mm (CE standards).
es: espesor
Transient
adjective
lasting only for a short time; impermanent.
Example: The effects of this change are anticipated to be transient.
