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...
Concentrating Solar Power (CSP) plants utilize oil, molten salt or steam as the heat transfer fluid (HTF) to solar energy power block. These fluids have properties that limit plant performance; for example, synthetic oil and upper temperature limits of approximately 390°C 565°C, respectively. While direct generation has been tested, it requires complex controls limited options integration thermal storage. Use carbon dioxide HTF cycle working offers potential increase efficiency while...
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...
A modeling methodology based on the coupling of free surface energy minimization techniques and computational fluid dynamics (CFD) has been developed for simulating macro-regime evaporation-driven self-assembly processes; specifically, those processes that use lithographically defined features to precisely direct particles a substrate. Because tension dominates gravitational, inertial, viscous forces acting droplet, shape droplet is determined as function its volume pinning geometry by...
