Abstract: 

Semi-empirical models are used to predict the power spectral density of wall pressure fluctuations in the turbulent boundary layer. From the analysis of current semi-empirical models and a large survey of experimental data, it was found that the models proposed by Goody and Smol'yakov have the lowest mean squared error when predicting the power spectral density for wind tunnel experiments. The Rackl and Weston model has the lowest mean squared error when predicting the power spectral density for flight test data. Current advancements in power spectral density wall pressure fluctuation prediction have expanded the range of experiments that can be predicted to include adverse pressure gradient flows, however, favourable pressure gradient flows have not received much attention. An experiment was performed to capture the effects of the favourable pressure gradient on the power spectral density. A model was created to improve upon some of the limitations of existing models.
