Flow dynamics and wall-pressure signature in high-Reynolds number overexpanded nozzle with free shock separation
E. Martelli, L. Saccoccio, P. P. Ciottoli +3
A delayed detached eddy simulation (DDES) of an overexpanded nozzle flow with shock-induced separation is carried out at a Reynolds number equal to 1.7 10^7. The flow unsteadiness,…
Data-driven decomposition of the streamwise turbulence kinetic energy in boundary layers. Part 2. Integrated energy and
Woutijn J. Baars, Ivan Marusic
Scalings of the streamwise velocity energy spectra in turbulent boundary layers were considered in Part 1. A spectral decomposition analysis provided a means to separate out attach…
Data-driven decomposition of the streamwise turbulence kinetic energy in boundary layers. Part 1. Energy spectra
Woutijn J. Baars, Ivan Marusic
In wall-bounded turbulence, a multitude of coexisting turbulence structures form the streamwise velocity energy spectrum from the viscosity- to the inertia-dominated range of scale…
Vertical Coherence of Turbulence in the Atmospheric Surface Layer: Connecting the Hypotheses of Townsend and Davenport
Dominik Krug, Woutijn J. Baars, Nicholas Hutchins +1
Statistical descriptions of coherent flow motions in the atmospheric boundary layer have many applications in the wind engineering community. For instance, the dynamical characteri…
