There has recently been a revival of interest in theories of liquid mixtures based on analytic equations of state for pure fluids. We have shown that the method used to determine the parameters of the pure-liquid equation of state has a significant effect on the excess thermodynamic properties obtained from such theories.

Abstract The economics of an ORC system is strictly linked to thermodynamic properties of the working fluid. A bad choice of working fluid could lead to a less efficient and expensive plant/generation unit. Some selection criteria have been put forward by various authors, incorporating thermodynamic properties, provided in literature but these do not have a general character. In the paper a simple analysis has been carried out which resulted in development of thermodynamic criteria for selection of an appropriate working fluid for subcritical and supercritical cycles. The postulated criteria are expressed in terms of non-dimensional numbers, which are characteristic for different fluids. The efficiency of the cycle is in a close relation to these numbers. The criteria are suitable for initial fluid selection. Such criteria should be used with other ones related to environmental impact, economy, system size, etc. Examples of such criteria have been also presented which may be helpful in rating of heat exchangers, which takes into account both heat transfer and flow resistance of the working fluid.

The Way

The paper discusses a possibility of application of dynamic vivacity function in interior ballistic process mathematical model. At present time, various technologies of powder grain surfacing are applied, mainly in case of powder grains used in assemblies of small-calibre cartridges. The grain surfacing can desirably influence the interior ballistic action. It can further change basic powder thermodynamic properties, and particularly, it can change the character of the powder grain burning, which cannot be described by geometric burning concept. According to the established standards, a necessity of the dynamic vivacity function L evaluation is determined for artillery powders only, but the way of its evaluation can be applied for arbitrary powder grains. The application of the dynamic vivacity function then allows to get results of solution of the interior ballistic tasks with higher accuracy, as well as the selection of suitable grain surfacing technology.
