Abstract
Results of simulations of the noise generated by a turbulent flow around a simplified rain gutter of a car windshield are presented. The hybrid approach of ANSYS FLUENT used the scale-resolving SBES model for calculating a turbulent flow under an incompressible flow assumption, and the wave equation model for the propagation of acoustic perturbations. The mean static pressure and the sound intensity obtained in the simulations were compared with experimental data and were found to be well predicted.
