Wall-pressure Fluctuations and Pressure-velocity Correlations in Turbulent Boundary Layers

Zero crossings of velocity fluctuations in turbulent boundary layers

In this paper some results are presented on the statistical properties of zero crossings of turbulent velocity fluctuations in boundary layers over a wide range of Reynolds numbers. The earlier finding that the probability density function (pdf) of the intervals between successive zero crossings of the streamwise velocity fluctuation u can be approximated by two exponentials, ,* each with its o...

Application of the velocity-dissipation probability density function model to inhomogeneous turbulent flows

Recently Pope and Chen [ Phys. Fluids A 2, 1437 ( 1990) ] developed a turbulence model based on the one-point Eulerian joint probability density function (pdf) of velocity and dissipation. The modeling is performed by constructing stochastic processes for the velocity and dissipation following fluid particles. In the original work, these models were constructed by reference to the known statist...
