Turbulent flow is a complex three dimensional system of velocity and pressure fluctuations in a fluid that creates vorticity, eddies and other flow structures. In this study we are specifically concerned with the surface pressure fluctuations below a turbulent boundary layer which is one of the primary sources of panel vibration on aircraft fuselages and ship hulls as well a major issue in ship hydrodynamics. The most accepted analytical approaches to describe the surface pressure fluctuations are the Chase model for the surface pressure wavenumber spectrum and Goody's model for the pressure spectrum at a point. The most accurate numerical approach to use is Direct Numerical Simulations (DNS). In this study we compared Chase and Goody's models against DNS of a turbulent channel flow in the space-time and wavenumber-frequency domains and estimated regions of convergence between the analytical models and the DNS data.
