Regenerative Brayton Cycle - an overview ScienceDirect Topics

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 is displaced with the cold fluid, which absorbs the heat. In regenerative heat exchangers, the fluid on either side of the heat exchanger can be the same fl… WebDownload scientific diagram Regenerator efficiency. from publication: Energy Efficiency Indicators for Assessing Construction Systems Storing Renewable Energy: Application to … WebDec 6, 2010 · Regenerator air distributor Catalyst and air distribution are important factors for improving regenerator efficiency.
