Flameless combustion represents a very appealing combustion technology due to its potential of coupling very high combustion efficiency with low NOx combustion emissions. However, due to its young character, the numerical modeling of flameless combustion is still characterized by open research questions, in particular related to the choice of the combustion model and of the kinetic mechanism. I...

We present an experimental investigation of the effect of kinetic energy on the ion doping efficiency of superfluid helium droplets using cesium cations from a thermionic emission source. The kinetic energy of Cs(+) is controlled by the bias voltage of a collection grid collinearly arranged with the droplet beam. Efficient doping from ions with kinetic energies from 20 eV up to 480 V has been o...

The influence of fluidic effects on two different kinetic parameter identifications in lab-scale catalysis testing was investigated using computational fluid dynamics. Firstly, the dry reforming of methane in a stagnation flow reactor with a detailed surface mechanism was simulated fully three-dimensional. It is shown that the 3D simulations are not advantageous over the commonly used stagnatio...
