The Thomson scattering in an ultraintense ( approximately 10(18) W cm(-2)) and ultrashort (20 fs) laser field is calculated that demonstrates different characteristics from those of the low-intensity field case. The electron trajectory no longer conforms to a figure-eight pattern, and the spectra demonstrate complex shifting and broadening to suggest that Thomson scattering can be used for char...

CO2/impurities cocapture in CCS technology allows reducing the purification costs and avoiding emission of pollutants into atmosphere. The viability transport by pipeline geological storage non-purified flue gas from oxy-fuel combustion biomass other processes, keeping impurities O2 or NO stream along with CO2, is assessed considering thermodynamic hydraulic aspects. For this, we experimentally...

Compact high-effectiveness Counter Flow Heat EXchangers (CFHEX) are crucial components of recuperative coolers, such as Joule-Thomson and Turbo-Brayton coolers remote cooling systems realised by a convective loop. This paper presents design analysis cryocooler-based system that extends the capabilities two-stage cryocooler. Increased heat exchange between high- low-pressure channels is establis...

Traditional thermoelectric cooling relies on the Peltier effect which produces a temperature drop limited by the figure of merit, zT. This cooling limit is not required from classical thermodynamics but can be traced to problems of thermoelectric compatibility. Alternatively, if a thermoelectric cooler can be designed to achieve full thermoelectric compatibility, lower temperature can be achiev...

To our knowledge, the potential use of CO2 as a heat-transmitting fluid for cooling applications in power plants has not been explored very extensively. In this paper, we conduct theoretical analysis to explore heat transmission fluid. We evaluate and compare thermophysical properties both dry air perform simple on steam-condensing device where steam flows through one flow paths (CO2 or air) is...
