Hydrodynamics of High Specific Power Pumps for Off-Design Operating Conditions

Part load operation of high energy centrifugal pumps is associated with increased vibration levels which may adversely affect the machines operational safety. The main sources of vibrations in centrifugal pumps are of hydrodynamic nature. The interaction b ...

Long-Term Monitoring Of Bright Blazars With A Dedicated Cherenkov Telescope

Mathieu Ribordy, Thomas Günther Bretz

Flaring activity of Active Galactic Nuclei (AGN) in VHE gamma-ray astronomy is observed on timescales from minutes to years and can be explained either by the interaction of relativistic jets with the surrounding material or by imprints of the central engi ...

Experimental investigation of prechamber autoignition in a natural gas engine for cogeneration

Daniel Favrat, Stefan Heyne

A novel ignition concept based on autoignition in an unscavanged prechamber is currently being developed at the Laboratory for Industrial Energy Systems (LENI). On a single cylinder test engine a series of experimental runs (CR=8.5-14, =1-1.6, RPM=1150/150 ...

Investigation of particles emitted from modern 2-stroke scooters

Philippe Buffat

Transmission electron microscopy (TEM), combined with X-ray energy dispersive spectroscopy (EDS)—both single and tandem differential mobility analyzer (TDMA)—have been used to investigate particles emitted by two modern 2-stroke scooters with different mix ...

Mechanism for blob generation in the TORPEX toroidal plasma

Jonathan Graves, Ambrogio Fasoli, Ivo Furno, Benoît Labit, Paolo Ricci, Stephan Brunner, Christian Gabriel Theiler, Mario Ludovico Podesta, Francesca Maria Poli

The mechanism for blob generation is detailed in the toroidal magnetized plasma of the TORPEX device [ Fasoli et al., Phys. Plasmas 13, 055902 (2006) ] using an experimental configuration, which features a plasma region dominated by a coherent wave and a r ...
