WebMay 22, 2024 · Heat Exchangers. Surface Condenser. Heat exchangers are devices that are used to transfer thermal energy from one fluid to another without mixing the two fluids. The fluids are usually separated by a solid wall (with high thermal conductivity) to prevent mixing or they may be in direct contact. The classic example of a heat exchanger is found ... A regenerative heat exchanger, or more commonly a regenerator, is a type of heat exchanger where heat from the hot fluid is intermittently stored in a thermal storage medium before it is transferred to the cold fluid. To accomplish this the hot fluid is brought into contact with the heat storage medium, then the fluid … See more The first regenerator was invented by Rev. Robert Stirling in 1816, and is also found as a component of some examples of his Stirling engine. The simplest Stirling engines, including most models, use the walls of the cylinder … See more Regenerators exchange heat from one process fluid to an intermediate solid heat storage medium, then that medium exchanges heat with a second process fluid flow. The two flows are either separated in time, alternately circulating through the storage … See more The major disadvantage of rotary and fixed-matrix regenerators is that there is always some mixing of the fluid streams, and they can not be … See more • Butz, J. S., Jr. (July 1962). "Engine economy through regeneration". Flying. Vol. 71, no. 1. pp. 44–45, 89–91. ISSN 0015-4806. • John H. Glenn Research Center (August 2006). See more The advantages of a regenerator over a recuperating (counter-flowing) heat exchanger is that it has a much higher surface area for a given volume, which provides a reduced exchanger volume for a given energy density, effectiveness and pressure drop.
