Abstract

Stochastic methods represent a highly efficient
way to recreate turbulent velocity fluctuations
based on Reynolds-averaged Navier-Stokes
(RANS) simulations. In this work, we present
how to compute source terms from the gener-
ated stochastic velocity field and how to apply
it to the aeroacoustic simulation of a deep cav-
ity with a lip to compute broadband noise and
aeroacoustic modes.
