Efficient Hybrid Computational Process for Aeroacoustic Vehicle Development Based on Navier-Stokes Equations and Lighthill's Acoustic Analogy

Vehicle interior noise at highway speeds is dominated by aerodynamic sources arising from unsteady turbulent flow around external components. Carlo Alberto Perugini presents a hybrid computational methodology for predicting aerodynamic noise sources and their contribution to interior cabin noise in road vehicles. His approach combines unsteady CFD simulations based on the incompressible Navier–Sto...
