The project is divided into four themes (Identification of hydrodynamic noise sources, optical signature of the wake of bubbles, hydro-acoustic modeling and characterization, modeling elasto-acoustic), has as its objective the development and validation of theoretical models and tools Computational analysis of optical and acoustic signatures of marine propellers. Characterization of the velocity field around a propeller-rudder system. Development of a camera DDPIV for measurement and verification of bubbles in cavitation tunnel acoustic signatures and optical propeller-rudder system. Development of numerical models for calculation of acoustic cavitating propellers. Development of methodologies for characterizing the transmission routes of the shaft vibration.
