Exergy is a combination property [6] of a system and its environment because it depends on the state of both and is a consequence of dis-equilibrium between them. Exergy is neither a thermodynamic property of matter nor a thermodynamic potential of a system. Exergy and energy always have the same units, and the joule (symbol: J) is the unit of ...
Thermogram of a traditional building in the background and a "passive house" in the foregroundInfrared thermography (IRT), thermal video or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science.
For example, the surveillance of people on a scene using a thermal imaging camera. active, in which an energy source is required to produce a thermal contrast between the feature of interest and the background. For example, internal flaws in an aircraft part may be identified by exciting the part with ultrasonic energy; the flaw responds to the ...
In principle, a targeted object or feature will have different thermal properties than its surroundings; for instance, a buried metallic pipe conducts heat more readily than the surrounding soil, so if the fluid it is carrying is at a different temperature than the ambient conditions, the pipe will be visible to a thermal imaging sensor without ...
Infrared vision is the capability of biological or artificial systems to detect infrared radiation.The terms thermal vision and thermal imaging [1] [2] are also commonly used in this context since infrared emissions from a body are directly related to their temperature: hotter objects emit more energy in the infrared spectrum than colder ones.
In thermal engineering, exergy efficiency (also known as the second-law efficiency or rational efficiency) computes the effectiveness of a system relative to its performance in reversible conditions. It is defined as the ratio of the thermal efficiency of an actual system compared to an idealized or reversible version of the system for heat ...
Non-contact thermography, thermographic imaging, or medical thermology is the field of thermography that uses infrared images of the human skin to assist in the diagnosis and treatment of medical conditions. Medical thermology is sometimes referred to as medical infrared imaging or tele-thermology and utilizes thermographic cameras. According ...
Where ‘exergy’ is the thermal, mechanical, electric or chemical work potential of an energy source or flow, and ‘instruction or intelligence’, is understood in the context of, or characterized by, the set of processes that are within category IV.
