(mechanical engineering)
(thermodynamics)
An engine cycle in which low-grade heat that would ordinarily be lost is used to improve the cyclic efficiency.

Experience of research, he believes, sets in a " regenerative cycle of excellence" in an educational institution.
This was the external combustion heat engine working on a closed regenerative cycle. It was so far in advance of contemporary scientific knowledge that it was more than 30 years before anyone could really understand how it worked.
For a conventional refrigeration or air-conditioning application, much higher temperature lifts are needed, so a regenerative cycle analogous to the active magnetic regenerator cycle in magnetocaloric refrigeration would be needed.
However, if properly planned and prepared for by a "vision" which accounts for the next stage of development, then a peak at 2008 can be, more importantly, part of a regenerative cycle.
If a cell scheduled for replacement is damaged, the body often shuts down that cell's regenerative cycle before a defective copy is made.
* Closed-loop cooling of the regenerative cycle avoids depositing water from atmospheric air while cooling a bed after regeneration.
* Closed-loop cooling of the regenerative cycle avoids depositing water from atmospheric air, while cooling a bed after regeneration.
As the best high energy permanent magnets can provide fields in the range of 1 to 2 T, achieving the temperature lifts needed for air conditioning and refrigeration requires the use of a regenerative cycle. In essence, the sensible heat cycling of the magnetocaloric material needs be provided by regenerative heat transfer and the magnetic field-induced temperature changes are used to remove heat from the cooling load and reject heat to the heat sink.
Of the belief that the very concept of "waste" can be eliminated, McDonough and Braungart, co-authors of Cradle to Cradle (North Point Press, $25), insist that human prosperity depends on learning to imitate nature's highly effective system of regenerative cycles. McDonough and Braungart, respectively an architect and a chemist, are eager to "remake the way we make things," and their highly regarded new book offers innovative design (the book's pages are made of tree-free, waterproof synthetic "paper") and an honest respect for the planet and its biodiversity.
Refrigeration and liquefaction - the production of low temperatures will be presented during the short course, including basic principles of low temperature production (the heat engine, efficiency concepts); Joule-Thomson expansion; isentropic expansion; and cryocoolers, regenerative cycles and pulse tubes.
However, the temperature change is so small that regenerative cycles with a liquid heat transport fluid as an integral part of the cycle are needed for any of the normal building air-conditioning or food refrigeration applications, so it is really a hybrid solid/fluid cycle.
