Experimental hydrodynamics

General details of the subject

Face-to-face degree course

Description and contextualization of the subject

Describe the experimental approaches used in Marine Renewable Energy studies. Involve the students into experimental campaigns in Ecole Centrale Nantes large scale facilities also used e.g. in European MRE research networks (MARINET) and international MRE research partnership (Univ. Osaka).

Direct applications of the concepts introduced in Water waves and sea states modelling course (environmental modelling), Wave-structure interactions course (structure response, diffraction-radiation, sea-keeping) and Moorings course (low-frequency response, mooring stiffness).

The pbjective is to provide students with state of the art knowledge on experimental fluid dynamics in the field of Offshore renewable energy. Despite the development of numerical modelling, the experimental approach remains a major source of knowledge development in ship hydrodynamics and marine renewable energy. The contribution to the selection of adequate hypothesis and to the validation of analytical or numerical models is of primary importance. In numerous situations, the experimental approach remains the most reliable, economical and fast way to validate new designs. Specific instrumentations and facilities are presented in this course and used in lab work.
