The investigation of flows in non-circular ducts of various sectional shape is of considerable engineering interest. In this paper, we perform simulations of the turbulent compressible flow in a duct of square cross section with streamwise curvature. The a ...
Using our recently developed technique of infrared laser assisted photofragment spectroscopy (IRLAPS), we have measured four vibrational overtone bands of jet-cooled CF3H in the N = 4 and N = 5 CH stretch-bend polyads. The cooling in the expansion eliminat ...
The voltages induced by nearby lightning strikes are a major cause of outages in power distribution systems. We compute such voltages taking into account the effects of the dart leaders that precede subsequent return strokes in both natural and rocket-trig ...
The effects and the consequences of transferring the ignition point of the conventional combustion chamber into a small unscavenged prechamber were evaluted through a numerical simulation based on the CFD-code KIVA- 3V. The prechamber flow characteristics ...
The third phase of upgrading of the superconductor test facility SULTAN into a split coil system (SULTAN III) is in progress. SULTAN III - a joint project of ENEA (Italy) and PSI (Switzerland) - consists of two coil packages, each containing three concentr ...
The combination of infrared-optical double resonance excitation with infrared laser assisted photofragment spectroscopy (IRLAPS) detection permits the measurement of rotationally resolved vibrational overtone spectra of jet-cooled CF3H. The IRLAPS detectio ...
The dispersion of nanosized gamma aluminas with high specific surfaces areas (100 m2 /g) and primary particle sizes around 20 nm, using polyacrylic acid, has been investigated. The effect of pH and polymer concentration showed that the highest density gree ...
