Heat exchanger for supercritical CO2 cycle - Mathematical modelling and validation on available experimental data.

This paper presents the model of heat exchanger dedicated to operate in supercritical CO2 cycles (Brayton). The models is built in the Ebsilon software and validated against literature available experimental data. Relatively compact design of the supercritical CO2 cycle elements required using radial turbomachinery and thin plate heat exchangers. Thus, it seems that there is no general relationships for the turbomachinery and real characteristics need to be used for constructing the models. [ABSTRACT FROM AUTHOR]
