2015/9/2
One of the typical methods for the identification of seismo-hydrological effects is to monitor changes in the free
gas flow throughout springs or mofettes. For several years, the gas flow regime of m...

Abstract: We determined the gas-flow reduction factor of the second forward Differential Pumping Section (DPS2-F) for the KATRIN experiment using a dedicated vacuum-measurement setup and by detailed m...
$L^\infty$ solutions for a model of polytropic gas flow with diffusive entropy
Polytropic gas di usive entropy

We establish the global existence of L1 solutions for a model of polytropic gas ow with di usive entropy. The result is obtained by showing the convergence of a class of nite di erence schemes, whic...

We present a simple hydrodynamic model to obtain the profiles of the relevant physical quantities along a nozzle of arbitrary cross-section in a cutting torch. The model uses a two-zone approximation ...
