Currently, the different pollutant emissions caused by the use of fossil energies are an increasingly important concern and numerous studies aim at developing technological solutions allowing the progressive replacement of the fossil energies by more susta ...
A heating stage has been developed to perform in-situ annealing in a SEM equipped with an EBSD system in order to study recrystallization mechanisms. High temperature treatments could then be performed inside the SEM, up to 1180°C and with high heating and ...
In the context of finding efficient and environmentally friendly solutions to energy pro- duction and consumption, this work presents a method for the systematic resolution of district energy problems using Multi-Objective Optimisation (MOO) methods. A dis ...
The report describes the implementation of a radial micro-compressor in the dynamic modeling software PSE gProms, the development and the implementation of a two-phase flow pipe model, and the preliminary design of a two-phase flow dynamic heat exchanger ...
This report presents a study of an enthalpy and exergy analysis in the framework of a district scale energy balance. Energy demand (heating, cooling and lighting) for buildings represents more than 30 % of the total worlds energy use. Main efforts have been ...
A new DSC-based experimental method to efficiently establish the glass transition temperature, Tg, vs. curing degree, α, relationship for structural adhesives was developed. The method approaches the continuous Tg-α relationship with a trilinear curve esta ...
After a brief review of the current research on the production of synthetic natural gas (SNG) from lignocellulosic biomass by gasification and methanation, this paper presents detailed thermo-economic process optimisation of the polygeneration of SNG, powe ...
This article presents an experimental study of upward flow boiling heat transfer in multiport tubes. Usually, multiport tubes are utilized horizontally in automotive and air-conditioning systems while here there is interest in vertical flow as part of a tw ...
Throughout the years LENI-EPFL spent a significant part of its research activities on heat pumps be it for industrial heat recovery or for domestic or district heating and cooling. Methodological contributions include the improvement of the formulation of ...
Peak load levelling through peak shaving and valley filling is need of the hour in the electricity grid network. A reserve plant or a large scale electric energy storage plant could be the way out to handle the variable load situations. Though the re- serve ...
