The models are built using Ebsilon software and validated against experimental data from available literature. Radial turbomachinery and thin plate heat exchangers were used to meet the demands of the relatively compact design of the S-CO 2 cycle elements. It seems that there are no general relationships for the turbomachinery and real characteristics need to be used for constructing the models. %U https://papers.itc.pw.edu.pl/index.php/JPT/article/view/1780 %J Journal of Power Technologies %0 Journal Article %P 1-13%V 102 %N 1 %@ 2083-4195 %8 2022-02-06
