When applying computational fluid dynamics (CFD) to the study of the wind noise, we create digital models and simulate airflow interaction.  CFD software 'solves' complex equations to predict fluid behavior, providing detailed visualizations of velocity and pressure fields.  This allows for the precise analysis of how air interacts with different structures - revealing the formation of turbulent eddies and pressure fluctuations that contribute to wind noise.

In addition, CFD simulations can be a tool for identifying more complicated wind noise reduction opportunities.
