This paper considers the relative merits of three optimization objective functions for the design of an energy efficient pervaporation membrane network for ethanol dehydration: the minimization of the standard deviation of the thermodynamic driving force, of the entropy generation, and of the power of separation. The resulting designs are compared with those of a standard numerical optimization...

The Density of State and the Natural Bond Orbital calculations were carried out to study theoxidation of CO on Au14 nano cluster through two different mechanisms and determining the bestmechanism for the reaction. Chemisorption of O2 and CO on the nano cluster led to change in energy,density of state and its thermodynamic properties. We calculated the energy band gap between thehighest occupied...

Concerns about limited energy resources and environmental problems are growing. One of the solutions to increase efficiency is produce it sparsely. In this regard, cogeneration systems particular importance. The home sector one most consumed sectors due potential solar radiation in country, a system simultaneous generation electricity heat for has been proposed, modeling operations have perform...

Renewable energy system is an important concern for sustainable development of the World. Thermodynamic analysis, especially exergy analysis is an intense tool to assess sustainability of the systems. Food processing industry is one of the energy intensive sectors where dairy industry consumes substantial amount of energy among other food industry segments. Therefore, in this study, thermodynam...

The objective of this paper is to provide a tool to facilitate the application of thermodynamic work potential methods to aircraft and engine analysis. This starts with a discussion of the theoretical background underlying these methods, which is then used to derive various equations useful for thermodynamic analysis of aircraft engines. The work potential analysis method is implemented in the ...

Enzymatic Reaction at the Single Molecule Level Moisés Santillán∗ Centro de Investigación y Estudios Avanzados del IPN, Unidad Monterrey, Parque de Investigación e Innovación Tecnológica, 66600 Apodaca NL, MÉXICO Abstract In this work we study, at the single molecular level, the thermodynamic and dynamic characteristics of an enzymatic reaction comprising a rate limiting step. We investigate ho...
