On the structure and origin of pressure fluctuations in wall turbulence: predictions based on the resolvent analysis [PDF]
We generate predictions for the fluctuating pressure field in turbulent pipe flow by re-formulating the resolvent analysis of McKeon & Sharma (2010) in terms of the so-called primitive variables. Under this analysis, the nonlinear convective terms in
