The double-regulated turbine comprises a spherical hub, adapted to rotate around a first rotation axis, and blades, which are each able to be swivelled relative to the hub around a second rotation axis, transversal to the first rotation axis, by respective coupling flanges that are mounted fixedly on the spherical hub and that include each an attachment surface for a corresponding blade. The attachment surface of the coupling flanges includes a flat portion.

Double-regulated turbine, installation for converting hydraulic energy and process for the rehabilitation of a double-regulated turbine

A turbine unit for a hydraulic installation, and more in particular it deals with the hub of the turbine unit. The present invention proposes to provide means for adjusting a gap extent formed between the hub and the inner edge of the blade, this way dramatically increasing the performance of the turbine.

Turbine unit for hydraulic installation

A heat exchange structure is provided, including a primary face provided with non-through holes formed in said face, the inner surface of the holes and the surface of said primary face outside the holes being covered with nanoparticles, the inside of the holes having a non-wettability property relative to a given liquid and the surface of the face between the holes having a wettability property relative to the liquid.

Heat exchange structure and cooling device comprising such a structure

A device forming a manometer, configured to measure pressure of a biphasic fluid in a fluidic network, including: a first channel inside which a biphasic fluid is able to flow; a second channel emerging into the first channel, wherein the second channel is blind, with each of its dimensions less than capillary length of the fluid's liquid phase, and with at least one of its lengthways wall having a surface energy gradient that decreases from its inlet to the end. The surface energy gradient enables the wetting angle of the meniscus of the fluid's liquid phase to be increased in the blind channel from its inlet to the end. Such a device may find application to measurement of pressure of a biphasic fluid in a heat exchanger or in a fuel cell.
