15 Heat Transfer terms
Electronic glossary with vocabulary and key concepts from the reading to get familiar with terminology.
- closed system
- Closed system definition, a region that is isolated from its surroundings by a boundary that admits no transfer of matter or energy across it.
- Example: Also, the simulation of a CLOSED SYSTEM with only one form of energy input is unlikely, with human intervention such as logging and fire fighting.
- en: sistema cerrado
- Conduction
- The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
- Example: The heat exchanger is insulated from its surroundings, the only heat exchange is between hot and cold fluids CONDUCTION along the walls is negligible Potential and kinetic energy changes are negligible.
- en: Conducción
- consist of
- Be composed or made up of.
- Example: It was discovered in tropical grasses (2) and is now known to CONSIST OF 17 higher family plants, and includes many important crop species including maize and sugarcane.

- Convection
- The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
- Example: You may be predicted from forced CONVECTION correlations.
- en: Convección
- Deal with
- to be about (something) : to have (something) as a subject Her speech dealt with health care and the nation's economy. The film deals with some serious issues. 2 : to make business agreements with (someone) He deals fairly with all his customers. Their salespeople are very easy to deal with.
- Example: To have increased staff competency in being able to DEAL WITH all types of insurance policy (except Life).
- en: Tratar con
- Fixed mass
- Closed system or control mass: consists of a fixed amount of mass, and no mass can cross.
- Example: On palpation a small FIXED MASS was detected, approximately 1.5cm in size.
- en: Masa fija
- Heat Transfer
- In general, heat transfer describes the flow of heat (thermal energy) due to temperature differences and the subsequent temperature distribution and changes.
- Example: Fouling causes extensive problems in the processing of milk as it reduces the efficiency of HEAT TRANSFER and can present microbiological problems.
- en: Transferencia de calor
- inner surface
- The environment beneath the surface of the sea. 2 the human mind regarded as being as unknown or as unfathomable as space. Inner Temple.
- Example: Upon the INNER SURFACE of the envelope, Matrix protein or M1 coats the entire surface, stabilising the particle structure.
- en: inner surface
- Internal energy
- Internal energy is defined as the energy associated with the random, disordered motion of molecules. It is separated in scale from the macroscopic ordered energy associated with moving objects; it refers to the invisible microscopic energy.
- Example: This means the system does work on its surroundings, and the change in INTERNAL ENERGY (U) is equal to the heat added (Q) plus the work done (W).
- en: Energía interna
- mass transfer
- Mass transfer is the net movement of mass from one location, usually meaning stream, phase, fraction or component, to another.
- Example: For example crystallisation, resolution of specific scale up issues for example agitation and heat MASS TRANSFER, and make sure engineering problems are not solved using chemistry.
- en: transferencia de masa
- open system
- A material system in which mass or energy can be lost to or gained from the environment.
- Example: In contrast to this Bhaskar advanced the view that reality is an 'OPEN SYSTEM' in which causal mechanisms (like gravity) interact with other causal mechanisms and can interrupt their causal effects.
- en: sistema abierto
- outer surface
- He outside part or uppermost layer of something. facade. surface. exterior.
- Example: The Biochemistry Of PhotosynthesisLight- Dependent Reaction: In both C 3 and C 4 plants, the chlorophyll molecules are arranged in the membranes of the thylakoids so that the haem group projects from the OUTER SURFACE.
- en: Superficie exterior
- Radiation
- The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
- Example: In such intensive systems, maximising the amount of Photosynthetically Active RADIATION (PAR) reaching the crop allows growers to maximise yields.
- en: Radiación
- Total energy
- The total energy of a system is the sum of kinetic and gravitational potential energy, and this total energy is conserved in orbital motion.
- Example: Theorem Bernoulli's theorem follows the law of conservation of energy and states that the TOTAL ENERGY in a fluid is a constant, neglecting any losses in transmission.
- en: Energía total
- undergo
- experience or be subjected to (something, typically something unpleasant, painful, or arduous).
- Example: The narrative continually forces the reader to re-asses their opinions, allowing them to UNDERGO a journey into the self.
