This paper investigates the thermal performance of a prismatic slab internally cooled by a bundle of staggered tubes. Four tube arrangements are considered, each case having three constructal levels of cooling tubes; for each case a single ratio between two consecutive tube level diameters is...

An exergy analysis of an advanced hypersonic vehicle, a scramjet, is presented and discussed with a twofold scope. First, to perfect the exergy approach to the design and optimization of aerospace propulsion systems: the exergy flow diagram can provide aircraft engineers and system designers...

When evaluating the production of renewable energies such as biofuels, it is necessary to include in the assessment the resource inputs, capital, labor investment and environmental remediation costs. Extended Exergy Accounting (EEA) is a system analysis method that calculates, on the basis of...

A model for the thermodynamic and thermoeconomic simulation of a MED desalination plant has been developed. As the code is embedded in a modular simulator, CAMEL©, it is relatively easy to use it for analyses of different plant configurations. CAMEL itself had been developed by the Mechanical...

Aim of this paper is to analyze the performance of an innovative high-efficiency steam power plant by means of two “life cycle approach” methodologies, the life cycle assessment (LCA) and the “extended exergy analysis” (EEA).

The Turkish society is analyzed, on the basis of a 2006 database, by means of the EEA (Extended Exergy Accounting) method. A brief synthesis of EEA is also presented, with the purpose of clarifying some of the issues related to its accounting technique. The system to be analyzed is assumed to be...
