Flow acoustic simulation with the Lattice-Boltzmann method

摘要

The invention relates to a method for describing and numerical simulating aeroacoustic properties of a fluid-structure system.;The method is characterized by comprising the steps of mathematical describing and calculating of a flow of the fluid, thereby generating results for using in mathematical describing and calculating of vibrations of the structure, numerical simulating of the flow, the structural behaviour and the interaction of both and optimizing of the system with regard to its aeroacoustic properties.The fluid dynamics part is solved by the Lattice-Boltzmann-Method. The structural mechanics part is solved by the Finite-Element-Method.
