heat transfer process
31Critical heat flux — describes the thermal limit of a phenomenon where a phase change occurs during heating (such as bubbles forming on a metal surface used to heat water), which suddenly decreases the efficiency of heat transfer, thus causing localised overheating… …
32Isentropic process — In thermodynamics, an isentropic process ( iso = equal (Greek); entropy = disorder ) is one during which the entropy of the system remains constant. [Van Wylen, G.J. and Sonntag, R.E., Fundamentals of Classical Thermodynamics , Section 7.4]… …
33Micro process engineering — is the science of conducting chemical or physical processes (unit operations) inside small volumina, typically inside channels with diameters of less than 1 mm (microchannels) or other structures with sub millimeter dimensions. These… …
34Plate fin heat exchanger — A plate fin heat exchanger is a type of heat exchanger design that uses plates and finned chambers to transfer heat between fluids. It is often categorized as a compact heat exchanger to emphasise its relatively high heat transfer surface area to …
35Dynamic scraped surface heat exchangers — Introduction The most important technologies for indirect heat transfer use tubes (shell and tube exchangers) or flat surfaces (plate exchangers). Their goal is to exchange the maximum amount of heat per unit area by generating as much turbulence …
36Micro heat exchanger — Micro heat exchangers, Micro scale heat exchangers, or microstructured heat exchangers are heat exchangers in which (at least one) fluid flows in lateral confinements with typical dimensions below 1 mm. The most typical such confinement are… …
37Dry heat sterilization — See also: Sterilization (microbiology) Dry heat sterilization of an article is one of the earliest forms of sterilization practiced. Dry heat, as the name indicates, utilizes hot air that is either free from water vapour, or has very little of it …
38Oxy-fuel combustion process — Oxyfuel CCS power plant operation Oxy fuel combustion is the process of burning a fuel using pure oxygen instead of air as the primary oxidant. Since the nitrogen component of air is not heated, fuel consumption is reduced, and higher flame… …
39Carnot heat engine — A Carnot heat engine [In French, Carnot uses machine à feu , which Thurston translates as heat engine or steam engine . In a footnote, Carnot distinguishes the steam engine ( machine à vapeur ) from the heat engine in general. (Carnot, 1824, p. 5 …
40Wireless energy transfer — or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous,… …
