Particles turbulence interactions in boundary layers [PDF]

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2005
AbstractTurbulent dispersed flows in boundary layers are crucial in a number of industrial and environmental applications. In most applications, the key information is space distribution of particles which is known to be strongly non‐homogeneous. Specifically, inertial particles distribute preferentially avoiding strong vortical regions and segregating

Countergradient Momentum Transport in Clear Convective Atmospheric Boundary Layers

open access: yesJournal of Advances in Modeling Earth Systems
The vertical profiles of the wind speed and direction in atmospheric boundary layers are strongly controlled by turbulence. Most global weather forecast and climate models parameterize the vertical transport of horizontal momentum by turbulent eddies by ...

Some characteristics of bypass transition in a heated boundary layer [PDF]

open access: yes
Experimental measurements of both mean and conditionally sampled characteristics of laminar, transitional and low Reynolds number turbulent boundary layers on a heated flat plate are presented. Measurements were obtained in air over a range of freestream

A Statistical Dynamic Model for the Turbulent Transport of Kinetic Energy in Shear Layers

open access: yesJournal of Aerospace Technology and Management, 2018
Dynamic statistical equations for the turbulent fluxes of scalars and momentum in incompressible flows are derived after time wise integration of the equation for the oscillating transported property, decomposing the turbulent fluxes in terms ...

Measurement and correlation of aerodynamic heating to surface corrugation stiffened structures in thick turbulent boundary layers [PDF]

open access: yes
The flow conditions for which heating distributions were measured on corrugated surfaces and wavy walls in turbulent boundary layers are shown, along with the ratio of the displacement thickness to the roughness height versus the local edge Mach number ...

Outline of research on oscillating boundary layers [PDF]

open access: yes
The state of the art in the field of unsteady boundary layers is outlined with emphasis on turbulent boundary layers. The unsteady flows considered are mainly periodic with the external velocity varying around a zero or nonzero mean time value.

Numerical study of supersonic turbulent flow over small protuberances [PDF]

open access: yes
Supersonic turbulent boundary layers over two-dimensional protuberances are investigated, using the numerical finite difference alternating direction implicit (ADI) method. The turbulence is modeled mathematically.

Anomalous diffusion in geophysical and laboratory turbulence [PDF]

open access: yesNonlinear Processes in Geophysics, 1994
We present an overview and some new results on anomalous diffusion of passive scalar in turbulent flows (including those used by Richardson in his famous paper in 1926).
