On the structure and origin of pressure fluctuations in wall turbulence: predictions based on the resolvent analysis

We generate predictions for the fluctuating pressure field in turbulent pipe flow by reformulating the resolvent analysis of McKeon and Sharma (J. Fluid Mech., vol. 658, 2010, pp. 336–382) in terms of the so-called primitive variables. Under this analysis, the nonlinear convective terms in the Fourier-transformed Navier–Stokes equations (NSE) are treated as a forcing that is mapped to a velocit...

Inner-outer Interaction Predictive Model for Wall-bounded Turbulence Subjected to Pressure Gradient Effect

In an early work, Marusic, Mathis & Hutchins (2010) developed a model ables to reconstruct the streamwise turbulence fluctuation of the inner-layer in zero-pressuregradient, flat-plate, turbulent boundary layer. The originality of this model, which is based on scales interaction, is that it requires as input only one localised information (e.g. one measurement point) about large-scale log-regio...

Statistics of pressure fluctuations in decaying isotropic turbulence.

We present results from a systematic direct-numerical simulation study of pressure fluctuations in an unforced, incompressible, homogeneous, and isotropic three-dimensional turbulent fluid. At cascade completion, isosurfaces of low pressure are found to be organized as slender filaments, whereas the predominant isostructures appear sheetlike. We exhibit several results, including plots of proba...

On the logarithmic region in wall turbulence

Considerable discussion over the past few years has been devoted to the question of whether the logarithmic region in wall turbulence is indeed universal. Here, we analyse recent experimental data in the Reynolds number range of nominally 2 × 104 < Reτ < 6 × 105 for boundary layers, pipe flow and the atmospheric surface layer, and show that, within experimental uncertainty, the data support the...
