In this work, the ability of Artificial Neural Network or ANN based on back-propagation algorithm to modeling and predicting of compressibility factor of natural gas has been investigated. The MSE analysis based on results, are used to verifying the suggested approach. Results show, a good agreement between experimental data and ANN predictions. An important feature of the model is its needless...
Negative compressibility is a sign of thermodynamic instability of open or non-equilibrium systems. In quantum materials consisting of multiple mutually coupled subsystems, the compressibility of one subsystem can be negative if it is countered by positive compressibility of the others. Manifestations of this effect have so far been limited to low-dimensional dilute electron systems. Here, we p...
The reoxidation rate of sponge iron pellets and briquettes and oxidation of pure iron powder with compressibility between 27% and 55% in air and within the temperature range 300-900°C has been investigated. Factors affecting the oxidation rate are presented. These include the effect of temperature, compressibility, and sintering of Fe-powder before and during the oxidation.
The effects of compressibility on Rayleigh-Taylor instability (RTI) are investigated by inspecting the interplay between thermodynamic and hydrodynamic non-equilibrium phenomena (TNE, HNE, respectively) via a discrete Boltzmann model (DBM). Two effective approaches are presented, one tracking the evolution of the local TNE effects and the other focussing on the evolution of the mean temperature...
