Supercritical carbon dioxide (SCO2) Brayton cycles have the potential to offer improved thermal-to-electric conversion efficiency for utility scale electricity production. These generated considerable interest in recent years because of this and are being considered a range applications, including nuclear concentrating solar power (CSP). Two promising SCO2 cycle variations simple with recuperation recompression cycle. The models described paper appropriate analysis optimization both...
This article presents a novel use of three-dimensional printed direct winding heat exchangers (3-D-DWHX) to improve the thermal management stator in high power density electric machines. The 3-D-DWHX is contact with windings, enabling continuous current densities. dielectric polymer for exchanger allows windings without an additional insulation material. By occupying otherwise unused space between double layer concentrated there no significant impact on electromagnetic design, and smaller...
Continuing efforts to increase the efficiency of utility-scale electricity generation has resulted in considerable interest Brayton cycles operating with supercritical carbon dioxide (S-CO2). One advantages S-CO2 cycles, compared more traditional steam Rankine cycle, is that equal or greater thermal efficiencies can be realized using significantly smaller turbomachinery. Another advantage heat rejection not limited by saturation temperature working fluid, facilitating dry cooling cycle...
Direct winding oil cooling offers more effective than conventional alternatives and can therefore increase the torque density of electric machines; however, this technique is limited by thermophysical properties oil. The use a direct heat exchanger (DWHX) allows glycol-water coolant mixture to be used which leads significant improvement in transfer reduction pumping losses compared cooling. This paper proposed ceramic 3D printed exchangers (3D-DWHX) significantly improve concentrated...

Active magnetic regenerative refrigeration (AMRR) systems represent an environmentally attractive alternative to vapor compression that do not use a fluorocarbon working fluid. The AMRR concept has previously been demonstrated using superconducting solenoid magnets are practical for small-scale commercial applications. However, recent prototypes more permanent have proved can produce cooling over useful temperature range with relatively low field. In addition, families of materials large...
