Turbulent flow noise modeling for under- and upperbody load and transmission analysis

The goal of TUMULT is to address the interactions between a flow and the structure of a transportation system (car, train, aircraft, ship, submarine…) and develop innovative test-based, numerical and hybrid techniques for modelling and analysing the aeroacoustic sources of noise and their transmission to the interior compartment. With the developments in TUMULT, we aim to 1) offer innovative test-based acoustic imaging techniques in order to meet the emerging needs in wind tunnel aeroacoustic testing, 2) combine steady CFD simulation with statistical and stochastic models to compute the pressure loading of a structure subjected to a turbulent flow, reducing in this way the global computational cost associated to broadband wind noise computations, and 3) combine numerical and test-based techniques to analyze the noise transmission to the cabin interior, allowing effective noise reduction measures during the whole vehicle development process, starting from the very early design stages.
