this glossary is made for understand better the key words of heat-transfer
BOUNDARY CONDICTIONS
Noun
are based on the requirements that the two bodies in contact must have the same temperature in the contact area and an interface cannot store energy
Example: the conditions of two or more bodies
es: CONDICIONES DE BORDE
EMISSIVITY
noun
is the proportion of thermal radiation emitted by a surface or object due to its temperature.
Example: the emissivity of that body is high
es: Emisividad
ENERGY BALANCE
Noun
An energy balance is an accounting of the contributions and energy consumption by a system to be studied.
Example: Use energy balance for know how much energy out and how much energy enter the system
es: BALANCE DE ENERGÍA
HEAT CONDUCTION EQUATION
Noun
the heat conduction equation is use for calcule the heat conduction of a body
Example: Use the heat conduction equation for calcule the time of heat conduction from one body to another
es: ECUACIÓN DE CONDUCCIÓN DE CALOR
HEAT FLUX
Noun
is the energy flux from a body to another
Example: the heat flux of the metal is very fast
es: FLUJO DE CALOR
HEAT TRANSFER COEFFICIENT
noun
it is how heat is conducted through a series of resistant media.
Example: the heat transfer coefficient is very important for the heat transfer
es: COEFICIENTE DE TRANSFERENCIA DE CALOR
INITIAL CONDITION
noun
is the first condition of a system or body before a process
Example: the initial velocity is the initial condition of a system
es: Condición inicial
INSULATION
Noun
is uses to control the temperature of a system or body
Example: this house needs insulation because is very hot
es: AISLAMIENTO
INTERNAL ENERGY
Noun
is the sum of: the internal kinetic energy, that is, of the sums of the kinetic energies of the individualities that form a body with respect to the center of mass of the system
Example: the internal energy that this system
es: ENERGÍA INTERNA
SPECIFIED TEMPERATURE
noun
the amount of heat that must be supplied to the unit mass of a substance or thermodynamic system to raise its temperature
Example: the specified temperature of that system is very high
es: TEMPERATURA ESPECIFICADA
TEMPERATURE
NOUN
Degree or thermal level of a body or the atmosphere.
Example: in this country the temperature is low
es: TEMPERATURA
thermal conduction
Noun
is the ability of a material to conduct heat.
Example: the thermal conduction of a metal is high
es: CONDUCCION TÉRMICA
THERMAL CONDUCTIVITY
noun
is a physical property of materials that measures heat conduction capacity.
Example: the thermal conductivity from an object
es: CONDUCTIVIDAD TÉRMICA
THERMAL DIFFUSIVITY
Noun
Thermal diffusivity measures the rate at which temperature changes within a substance.
Example: the thermal diffusivity of each system is different
es: DIFUSIVIDAD TÉRMICA
THERMAL SYMMETRY
Noun
the temperature distribution in one half of it will be equal to that of the other half.
Example: the thermal symmetry that these object are the same
