Title: Performance estimation on micro gas turbine plant recuperator
Abstract: In order to accomplish a thermodynamic analysis of a micro gas turbine plant, while satisfying conditions related to different configurations, different input data sets and a series of imposed thermodynamic parameters, assumptions are necessary regarding the individual performance of the components, for enabling the correlation of overall performance with the performance of the components.The use of a recuperator, even if it can improve a micro gas turbine cycle efficiency, by reducing the fuel consumption for an imposed turbine inlet temperature, will induce a pressure loss on the hot and cold sections, with possible negative influence on the cycle efficiency.In order to investigate this pressure loss, a numerical study was conducted on several cases, by modifying the geometry of a simplified recuperator, using as input a reference micro gas turbine thermodynamic cycle.The comparison between the different results led to the quantification of recuperator's performance as a function of its geometry.
