Optimization of micro gas-turbine-recuperator heat transfer surface

Making highly efficient recuperator, that will have minimal dimensions, high recovery rate, and low-pressure loss is one of the key tasks in a micro gas turbine design process. This paper presents recuperator with Frenkel-type heat-exchange matrix. Design and dimension choice of envelopes, which comprise recuperator heat-exchange surface is validated through gas-dynamic calculations, which are described in this paper. © 2018 Institute of Physics Publishing.
