Autor: Emmanuelle Lopez, Bertram Velichorpillai, Pierre Roumieu, Claude Rebattet, Fabrice Loiseau, Olivier Bertrand

Publikováno v: Advances in Hydroinformatics ISBN: 9789812876140

In 2010, hydraulic energy represented 80 % of renewable energy production in France. It has the advantage of being highly adaptable to the demand placed on the network, in contrast to solar and wind energy. However, most potential production sites ar

Dynamic Vapour Fraction Measurement in Turbopump Inducers by X-Rays

Autor: Stéphane Barre, Walid Hassan, Samuel Legoupil, Claude Rebattet

Publikováno v: Volume 2: Fora.

This work intended to evaluate the instantaneous vapour fraction in the turbo-pump inducer of a liquid propellant rocket engine. Experimentations held on an experimental pump test facility and cavitation was attained by reducing the inlet pressure in

Effect of the Leading Edge Design on Sheet Cavitation Around a Blade Section

Autor: Jean-Luc Reboud, Philippe Morel, Claude Rebattet

Publikováno v: Hydraulic Machinery and Cavitation ISBN: 9789401093873

An experimental study of the cavitation behaviour of two-dimensional hydrofoils simulating a section of an inducer blade has been performed in the CREMHyG large cavitation tunnel. Two leading edge shapes, chosen at the request of the SEP to approach
