SmartAnswer courses - Rotating Machines

Du lundi 26 au vendredi 30 mars 2018, ECL, bât W1, amphi 1bis

SmartAnswer is a European MARIE SKŁODOWSKA-CURIE project (for ‘Smart mitigation of flow-induced acoustic radiation and transmission for reduced aircraft, surface transport, workplaces and wind energy noise’). This project aims at developing innovative technologies for flow and acoustic control, in a view to provide better passenger comfort and reduced environmental impact in air and surface transportation, for quieter domestic appliances and systems on homes and working places, and more sustainable wind energy production.
