The energy integration of industrial processes is becoming increasingly more effective thanks to new methodological developments such as pinch technology. This paper aims at extending the number of factors considered in pinch analysis toward a life-cycle o ...
In the frame of the decentralised electrical power and heat cogeneration with stationary I. C. engines operating on natural gas, the Swiss limit for exhaust gas emissions, with 80 mg/mN3 (5% O2), is the most severe in force on an international level. On th ...
Lack of precision and inconsistencies in existing correlations, an attempt was successfully made to develop a new and more mechanistically based correlation (Kattan, 1996 [1]) for boiling inside plain tubes. This new general correlation is original in that ...
Combined cycle power plants burning natural gas offer various advantages such as high efficiency, low environmental impact, smaller specific investments and shorter construction periods which lead to a more flexible response to uncertain future electricity ...
The integration of a solar collector field generating steam into a conventional combined cycle in order to partially replace the fossil fuel required by the latter results in a substantial reduction in greenhouse gases, in an increase in the return on inve ...
Eine Verbesserung unserer Wettbewerbsfähigkeit erfordert nicht nur die Entwicklung neuer und leistungsfähigerer Produkte, sondern im Hinblick auf eine rationellere une umweltschonendere Produktion auch die Verbesserung von Konzeptionsmethoden für Ingenieur ...

For the most part, district heating demands can be met by an appropriate intergration of cogeneration and heat pumps units provided that advantages is taken of the fact that many urban regions are concentrated around surface waters. Despite the fact that t ...
A summary of the objectives and conclusions reached in this project are: •A litterature search on post dryout heat transfer for pure refrigerants and for refrigerant-oil mixtures was performed and a comprehensive review written (Chapters 9, 10, and 11); •T ...
The substitution of CFC refrigerants in refrigeration systems, heat pumps and organic Rankine cycles for heat recovery, requires good methods for predicting heat transfer of substitute fluids. The measurements in the LENI test facility (concentric tubes wi ...
