Durabilité des composites pour énergie marine renouvelable
Provedor de dados: 5
Autores: Davies, Peter; Boisseau, A.; Choqueuse, Dominique; Thiebaud, F.; Perreux, D.
Composites will play an essential role in the development of ocean energy conversion systems, and their long term durability is critical to the success of these structures. Composites have been widely used in marine applications and in structures highly loaded in fatigue such as wind turbine blades. However, very few data are available to evaluate their performance under conditions which combine long term immersion in sea water and sustained cyclic loading. In this study composites reinforced with three different types of glass fibre and the same epoxy resin have been tested under these conditions, and the influence of aging on both static and fatigue behaviour has been quantified. Fibre type, resin and fibre/resin interface all influence the fatigue...

Parameters of the hydro-mechanical mixer for diesel biofuel production
Provedor de dados: 111
Autores: Golub, Gennadii.
The rational design and technological parameters and modes of operation of the hydro-mechanical mixer for the production of diesel biofuel are experimentally determined. The dependence of the influence of the nozzle diameter, the rate of turn-over of the pump shaft of the mixture delivery and the angle of inclination of the blades on the rate of turn-over of the hydro-mechanical mixer is established. The equations for determination of kinematic viscosity, flash point and generalized indicator of diesel biofuel quality are obtained. The influence of the structural and technological parameters of the hydro-mechanical mixer on the specific energy consumption, power consumption and quality of diesel biofuel is determined.
