Comparisons of the Acoustics Models for the Numerical Simulations of Wind Noise

The methods that solve the flow equations and the acoustics equations separately are often applied to the aeroacoustics simulations. Although the acoustics simulations are generally applied to the far fields, this paper concerns about the near fields to predict the wind noise observed on the surfaces of automobiles. The acoustic fields obtained by the non-linear, linear, and Lighthill analogy models are compared around a two dimensional cylinder. Furthermore, the acoustic fields around the side window of an automobile are calculated. This paper shows the characteristics of each model with the detailed analysis of the wave profiles.
