Efficiency formulations are explained for most important engineered devices such as turbines, compressors, pumps, chemical reactors, and psychrometric processes. Study Problems 1.1. Explain the difference between flow work and boundary work. 1.2. Explain the difference between closed and open thermodynamic...
Only because has a negative part and a positive part , its absolute value corresponds to the area enclosed by the cycle in the PV diagram.Mar 28, 2017 #5 DrClaude Mentor 8,460 5,654 greypilgrim said: I'm not sure if we are talking about different things, but I can't think...
Reliable thermodynamic and physical data are essential to achieve a high accuracy in the simulation of chemical processes. Thermodynamic data in this work was calculated using AP. The UNIQUAC model was used to calculate the activity of all components in the liquid phase and the Hayden O'Connell ...

Methods Density and other derived thermodynamic properties using GERG-2008 Equation of State (EoS). To efficiently design and operate the technical processes involved in gas-based energy industries, precise rep- resentation of the thermodynamic properties using an accurate EoS is essential. Here,...
In practice, the thermodynamic processes are irreversible and entropy generation will be produced. The concept of entropy generation can measure the irreversibility of thermodynamic processes, and the entropy generation minimization can lead to the minimum loss of the ability to do work minimum, so som...
There exist a large number of ‘phenomenological laws’ describing irreversible processes in the form of proportionalities, such as Fick's law between the flow of a substance and its concentration gradient, and the mass action law between the reaction rate and affinities. When two or more of th...

By applying nonequilibrium thermodynamics theory to exergy analysis, the paper aims to derive the common relation between the rate of exergy destruction and the driving forces and expound the mechanism of exergy destruction caused by irreversible processes. 将非平衡态热力学理论应用于 分析,导出了 损...
