.SolarTherm.Models.PowerBlocks.sCO2Cycle.OnDesign.Cycles.simpleRecupCycleExchanger .SolarTherm.Models.PowerBlocks.sCO2Cycle.OnDesign.Cycles.simpleRecupCycleExchangerOn-design model of a simple recuperation cycle with an exchanger HTF/sCO2.
The number of discretization of the recuperators ought to be discussed, as the Cp is not a constant and therefore the TLMD is not totally pertinent. The heat recuperator DTAve can be used as well. Results are very close. The discussion is more on the number N_q of elements (N_q=15 vs 40: 2°C difference at the outlet).
Some attention has to be given to the source model (temperature, etc.).
The mass flow is imposed by the electrical power output given as a parameter. The relation between mass flow of the HTF and CO2 is determined relatively to the Cp of each fluid.
A financial analysis is performed based on estimation of the different costs, from Brun et al.
An exergy analysis is implemented based on a class from Pr. Neveu (UPVD).
