Phase-field simulation of micropores constrained by a solid network

Alain Jacot, Milan Felberbaum, Hossein Meidani

A 2D phase-field model has been developed in order to describe the morphology of a pore forming within interdendritic liquid channels and the geometrical effect of mechanical contacts with neighboring solid. The distribution of the solid, liquid and gas ph ...

Gas Detection with a Micro FTIR Spectrometer in the MIR Region

Nico de Rooij, Hans Peter Herzig, Danick Briand, Toralf Scharf

We report on the application of a silicon micromachined lamellar grating interferometer in a Fourier Transform Infrared (FTIR) spectrometer for the detection of gases in the mid-infrared (MIR) region. The FTIR spectrometer was equipped with MIR optical fib ...

Compactness of cold gas in high-redshift galaxies

Danail Obreschkow

Galaxies in the early Universe were more compact and contained more molecular gas than today. In this paper, we revisit the relation between these empirical findings, and we quantitatively predict the cosmic evolution of the surface densities of atomic (HI ...

Cold gas in the Perseus cluster core: excitation of molecular gas in filaments

Yves Revaz

We have recently detected CO lines in the well-known filaments around NGC 1275, the galaxy at the centre of the Perseus cluster of galaxies. These previous observations, with the HERA multi-beam array at the IRAM 30 m telescope enabled us to make a large m ...

Observations of CO in the eastern filaments of NGC 1275

Yves Revaz

We recently found extended CO(2-1) emission from cold molecular gas embedded in the network of Ha filaments surrounding the galaxy NGC 1275 (Salome et al. 2006). We now present CO(2-1) interferometer maps of the eastern filaments, at high spatial and spect ...

Local current measurement in a solid oxide fuel cell repeat element

Daniel Favrat, Jan Van Herle, Nordahl Autissier, Diego Larrain

A planar solid oxide fuel cell repeating unit, 50 cm2 in total active electrode size, consisting of an anode supported electrolyte cell bearing two 7 mm holes for fuel and air injection, and contacted to two dense metal current collector plates ...

Multi-Objective Optimisation of Herringbone Grooved Gas Bearing Supporting a High Speed Rotor, Taking into account Rarefied Gas and Real Gas Effects

Daniel Favrat, Jürg Alexander Schiffmann

Currently the herringbone grooved journal bearing (HGJB) has applications in the domain of small, low power energy related applications, where high rotational speeds are required for reaching reasonable efficiency and where standard oil lubricated bearings ...

Numerical simulation of free surface incompressible liquid flows surrounded by compressible gas

Jacques Rappaz, Marco Picasso, Alexandre Caboussat

A numerical model for the three-dimensional simulation of liquid-gas flows with free surfaces is presented. The incompressible Navier-Stokes equations are assumed to hold in the liquid domain. In the gas domain, the velocity is disregarded, the pressure is ...

Characterization of supersonic low pressure plasma jets

Malko Gindrat

Low Pressure Plasma Spraying (LPPS) processes use a DC plasma jet expanding at low pressure for fast deposition of dense coatings in a controlled atmosphere. The LPPS technology is widely used industrially in particular in the aeronautics and medical indus ...
