Parameters of state in the global thermodynamics of binary ideal gas mixtures in a stationary heat flow [PDF]

arXiv, 2023
We formulate the first law of global thermodynamics for stationary states of the binary ideal gas mixture subjected to heat flow. We map the non-uniform system onto the uniform one and show that the internal energy $U(S^*,V,N_1,N_2,f_1^*,f_2^*)$ is the function of the following parameters of state: a non-equilibrium entropy $S^*$, volume $V$, number of

Thermodynamic cycle with two-component working fluid

Environment. Technology. Resources. Proceedings of the International Scientific and Practical Conference, 2015
<p>The article deals with the implementation of the thermodynamic cycle using the two-component working fluid. An estimated calculation of the efficiency of using the two-component working fluid, and a variant implementation of the thermodynamic cycle rotary vane engine with an external heat supply are described.</p>

On the geometrical thermodynamics of chemical reactions [PDF]

arXiv, 2005
The formal structure of geometrical thermodynamics is reviewed with particular emphasis on the geometry of equilibria submanifolds. On these submanifolds thermodynamic metrics are defined as the Hessian of thermodynamic potentials. Links between geometry and thermodynamics are explored for single and multiple component, closed and open systems.

Exploitation of a special-relativistic entropy identity for one component of a multi-component system [PDF]

arXiv, 2017
Non-equilibrium and equilibrium thermodynamics of an interacting component of a special-relativistic multi-component system is discussed by using an entropy identity. The special case of the corresponding free component is considered.

A thermodynamically consistent pseudo-potential lattice Boltzmann model for multi-component, multiphase, partially miscible mixtures [PDF]

arXiv, 2019
Current multi-component, multiphase pseudo-potential lattice Boltzmann models have thermodynamic inconsistencies that prevent them to correctly predict the thermodynamic phase behavior of partially miscible multi-component mixtures, such as hydrocarbon mixtures.
