An ecological optimization along with a detailed parametric study of an irreversible regenerative Brayton heat engine with isothermal heat addition have been carried out with external as well as internal irreversibilities. The ecological function is defined as the power output minus the power loss (irreversibility) which is ambient temperature times the entropy generation rate. The external irr...

Wrought and additively manufactured (AM) 316 L stainless steel samples were exposed to a simulated Brayton cycle supercritical CO2 (sCO2) environment, at temperature of 450 °C pressure 76 bar in 99.999% for 2 weeks. The ground surfaces wrought AM specimens had average oxide thickness 95 51 µm, respectively, composed primarily Fe Cr oxides. An as-printed sample was also the sCO2 environment exhi...

A modular DCLL blanket is selected as the reference concept in the ARIES-CS power plant study. This concept is characterized by the following features: 1. Eutectic lead lithium alloy Pb-17Li serving as breeder and coolant (“self-cooled breeding zone”); 2. Helium-cooled FW and blanket structure made of the MF82H Reduced Activation Ferritic Steel (RAFS); 3. Flow channel inserts (FCI) made of SiCc...

Abstract A thermodynamic analysis of a hybrid gas turbine solar plant, represented in three basic subsystems related to the power cycle, combustion chamber subsystem, and concentrator allows evaluating performance cycle from reduced number parameters, which include energy losses each its components. The radiation values are estimated with an evaluated validated theoretical model, uses natural a...

The article deals with the study on efficiency of units for porous ammonium nitrate production. ways which increase effective implementation energy resources are determined by including ejector recycling module, heat and mass exchangers that utilize principles regenerative indirect evaporative cooling, sub-atmospheric inverse Brayton cycle. Mixed exergy analysis evaluates all flows system conto...
