It expresses the pressure P of a gas in local equilibrium as a power series of the density. This equation may be represented in terms of the compressibility factor, Z, as This equation was …

2023年4月28日 · These empirical equations are called virial equations. As indicated, the parameters are functions of temperature. The values of \(B^*\left(T\right)\), \(C^*\left(T\right)\), …

effective equation of state (EOS). For example, one may add to the ideal-gas EOS (1) higher-order terms in pressure p or density . One then arrives at a virial expansion in p, p·V = Nk B T …

维里方程是海克·卡末林·昂内斯 (Heike Kamerlingh Onnes)于1901年提出的以幂级数形式表达的实际气体状态方程，它是对理想气体状态方程式进行了修正的纯经验方程。

维里状态方程的应用 由于缺少高阶Virial 系数，在热力学性质计算，通常是采 用截取二项或三项的近似Virial EOS 。 如果流体的压力P<0.5 MPa，用二项Virial EOS

2025年2月15日 · Therefore, this study newly developed a framework to model supercritical oxidation in JSRs by incorporating ab initio multi-body molecular potentials and high-order …

Freely sharing knowledge with learners and educators around the world. Learn more. Lecture notes on the virial equation of state.

2011年4月10日 · A Virial Coefficient is a term used in the Virial Equation of State to express deviations from the ideal gas law due to intermolecular forces. These coefficients, such as B, …

In these notes, we introduce the virial expansion using elementary mathematical methods. The reader needs to be only familiar with the contents of rst- and second-year university courses. A …

The standard form of the Virial EoS formulates the compressibility as an infinite series of the inverse molar volume or pressure, as shown by Equations (5.3) and (5.4). In the low-pressure …
