    Abstract
    In this investigation, wall-pressure fluctuations due to a turbulent boundary layer are estimated by various numerical methods. Four different turbulence models, including one- and two-equation models and a recently developed direct numerical simulation scheme, are employed to calculate the pressure and velocity fluctuations. Numerical results are compared with each other as well as with several empirical/semi-empirical mean-square-pressure models and single-point wall-pressure spectrum models. Among all investigated turbulence models, the delayed detached-eddy simulation based on Spalart-Allmaras (DDES-SA) model provided the most-accurate results in association with slope prediction in low-frequency range. Moreover, computation time of the DDES-SA model was shorter than other turbulence models. Comparison of the solutions of the proposed direct numerical simulation scheme and the DDES-SA model shows that the direct numerical simulation scheme provided more-accurate results, especially in the low-frequency region.
