Abstract

A study was conducted to develop an analytical framework for the prediction turbulent boundary layer (TBL)-induced noise into transport vehicle cabins and validate it. A model was proposed that considered the cross pressure power spectral density (PSD) of the stationary and homogeneous TBL wall pressure field over a flat panel, for zero pressure, and in a separate form. A number of other models were proposed in the study including a structural model and an acoustic model to conduct more investigations.
