We consider the problem of reconstructing superimposed temperature and wind flow fields from acoustic measurements. A new technique based solely on acoustic waves propagation is presented. In contrast to the usual straight ray assumption, a bent ray model ...
The Retarding Field Analyser (REA) is essentially the only practical tool for the measurement of ion energies parallel to the total magnetic field in the tokamak scrape-off layer plasma. One such device has recently been successfully employed at JET [1]. I ...
A multi-probe system has been developed to investigate the importance of electron temperature fluctuations turbulent transport in the Joint European Torus boundary plasma. The compact five-pin triple probe has been designed to reduce the phase delay of flu ...
The links between air pollution gas phase chem., aerosol chem. processes, and solar radiation are calcd. to improve air quality models. Air quality models are used to simulate pollutant content of the city plumes such as for Los Angeles. ...
We report findings of large metal grains (~150 um) with distinct zoning patterns in Ni, Co, Cr, and Si in CH chondrites which are consistent with a condensation origin from a gas of solar composition. ...
Thermal solar power plants using Rankine cycles closely approach the present economical electricity prices, at least in the large power range. One of the advantages currently explored is the integration with other fuel based technologies in order to ascert ...
Integrated solar combined cycle systems (ISCCS) represent, both economically and energetically, a promising alternative for the conversion of solar energy while offering a guarantee of a minimum power supply independant of the level of solar radiation. The ...
Some FeNi metal grains, similar to 150 mu m in apparent diameter, in CH carbonaceous chondrites are concentrically zoned in Ni (similar to 5-10 wt%), Co (0.2-0.4 wt%), and Cr (0.3-0.8 wt%); Silicon is present at the similar to 0.1 wt% level. These observat ...
Water diversion for hydroelectric power generation impacts the temperature of mountain streams. Such changes are estimated by using a coupled one-dimensional dead-zone heat balance model. In very steep river sections, the dissipation of kinetic energy is t ...
This report presents the field tests synthesis of a small Hybrid Solar Power Plant integrating three technologies : hermetic volumetric scroll expander - generators working with two superposed Organic Rankine Cycles (ORC) a cogeneration group composed by a ...
