Driving and Filling Personal Vehicles – The Questions of Energy - and Power - Density ( A Fast Filling Station for the Compressed Air Car )

Alfred Rufer, Mahbod Heidari, Arnaud Leuba

In the context of the development of zero emissions personal vehicles, compressed air cars have been proposed, as alternative solutions to electric solutions, with a small energy content leading to a limited range, but with interesting properties regarding ...

Integrated SMD pressure/flow/temperature multisensor for compressed air in LTCC technology: Thermal flow and temperature sensing

Peter Ryser, Thomas Maeder, Yannick Sébastien Fournier, Nicolas Craquelin, Jean-Bastien Coma

In this work, we present and analyse the flow-sensing part of a recently-developed multisensor in LTCC (low- temperature co-fired ceramic) technology; this device integrates flow / pressure / temperature sensing and is designed for diagnostics monitoring o ...

A multi-scale multi-physics model of soil drying

Lyesse Laloui, Hervé Péron

Drying shrinkage is modeled at a microscale as a two-stage process of deformation and evacuation of a two-tube vessel system, based on porosimetry evolution. In the first stage water flow is driven by an external evaporation flux. Flow is associated with a ...

Operating characteristics of constant-pressure compressed air energy storage (CAES) system combined with pumped hydro storage based on energy and exergy analysis

Daniel Favrat

Energy storage systems are becoming more important for load leveling, especially because of the widespread use of intermittent renewable energy. Compressed air energy storage (CAES) is a very promising method for energy storage because CAES relies on exist ...

"Compressed" Compressed Sensing

Michael Christoph Gastpar

The field of compressed sensing has shown that a sparse but otherwise arbitrary vector can be recovered exactly from a small number of randomly constructed linear projections (or samples). The question addressed in this paper is whether an even smaller num ...

Electrodeposition of Fe Powder from Citrate Containing Electrolytes

Polarization characteristics of the electrodeposition processes of Fe powders from different citrate electrolytes and the morphology of the obtained powders were investigated. The effect of complexing agents on the cathodic polarization, the current effici ...

Design, experimental investigation and multi-objective optimization of a small-scale radial compressor for heat pump applications

Daniel Favrat, Jürg Alexander Schiffmann

The main driver for small scale turbomachinery in domestic heat pumps is the potential for reaching higher efﬁciencies than volumetric compressors currently used and the potential for making the compressor oil-free, bearing a considerable advantage in the ...

SMD pressure and flow sensors for industrial compressed air in LTCC technology

Peter Ryser, Thomas Maeder, Yannick Sébastien Fournier, Grégoire Boutinard Rouelle

In this work, we propose an SMD (surface mount device) pressure sensor in LTCC technology specially designed for standard industrial compressed air. It combines the measurement of pressure and temperature, with its integrated signal conditioning electronic ...

Multistage hydraulic gas compression/expansion systems and methods

Alfred Rufer

Multistage hydraulic systems and methods for converting the potential energy of a pressurized gas, particularly air, into mechanical work operating in motor, and for producing compressed gas from the mechanical work of the rotating shaft (A1.1 ) when rotat ...
