Abstract

Within the framework of the Gibbs statistical theory, the issue of the size distribution of particles forming a statistical system and the moments of this distribution are considered. The size distribution of particles and the moments of this distribution are determined from probabilistic considerations. The particle size depends on the interactions in the system, the compressibility factor, the number of interacting particles, and the volume of the system. The relations for the average particle size are substituted into expressions for the intrinsic volume of particles in the equations of state written using excluded volume theory for various expressions for the exclusion factor. The equations of state obtained in this way can be considered as a refinement of the equation of state for dense systems, that is, as a transition to a higher level of description.

吉布斯系统中粒子的状态方程和粒度分布
摘要 在吉布斯统计理论的框架内,考虑了构成统计系统的粒子的大小分布和该分布的矩的问题。粒子的大小分布及其分布矩是根据概率考虑确定的。颗粒大小取决于系统中的相互作用、压缩系数、相互作用颗粒的数量以及系统的体积。将平均粒径关系代入使用排除体积理论写成的状态方程中的粒子固有体积表达式中,可得到排除因子的各种表达式。通过这种方法得到的状态方程可视为致密系统状态方程的改进,即过渡到更高的描述水平。

期刊介绍: High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
