Dissipative waves in real gases [PDF]

International Journal of Non-Linear Mechanics, 2017
In this paper, we characterize a class of solutions to the unsteady 2-dimensional flow of a van der Waals fluid involving shock waves, and derive an asymptotic amplitude equation exhibiting quadratic and cubic nonlinearities including dissipation and diffraction.

Method for Determining the Concentration of Unknown Combustible Gas

Proceedings, 2017
It is known that catalytic sensors have different sensitivities to different combustible gases. Usually gas analyzers are calibrated by methane and not suitable for measuring other flammable gases.

Lattice model of gas condensation within nanopores

, 2002
We explore the thermodynamic behavior of gases adsorbed within a nanopore. The theoretical description employs a simple lattice gas model, with two species of site, expected to describe various regimes of adsorption and condensation behavior.

Heat and Gravitation. III. Mixtures [PDF]

, 2010
The standard treatment of relativistic thermodynamics does not allow for a systematic treatment of mixtures. It is proposed that a formulation of thermodynamics as an action principle may be a suitable approach to adopt for a new investigation.
