Nаziv: | Entropy growth and entropy production rate in binary mixture shock waves | Аutоri: | Mađarević Damir Simić Srboljub |
Dаtum izdаvаnjа: | 2019 | Čаsоpis: | PHYSICAL REVIEW E | Sažetak: | © 2019 American Physical Society. Entropy growth and entropy production rate are analyzed in the stationary shock waves in a multitemperature model of a binary mixture of gases. The model is developed within the framework of extended thermodynamics. It is shown that the entropy density of the mixture increases monotonically through the shock profile, whereas the entropy densities of the constituents may not be monotonic. The analysis of entropy growth rate distinguished the contributions of momentum exchange (diffusion) and internal energy exchange between the constituents, and showed a substantially larger contribution of diffusion. At the same time, it is shown that the entropy production rates of the constituents may not be non-negative throughout the whole shock structure. | URI: | https://open.uns.ac.rs/handle/123456789/19962 | ISSN: | 2470-0045 | DOI: | 10.1103/PhysRevE.100.023119 |
