An experimental study of the properties of surface pressure fluctuations in strong adverse pressure gradient turbulent boundary layers [PDF]

Experimental data were obtained on blade self-noise generation by strong adverse-pressure-gradient attached boundary layers and by separated turbulent boundary layers that accompany stall.

Spectral analysis of boundary layers in Rayleigh-Benard convection

, 2007
A combined experimental and numerical study of the boundary layer in a 4:1 aspect-ratio Rayleigh-B\'{e}nard cell over a four-decade range of Rayleigh numbers has been undertaken aimed at gaining a better insight into the character of the boundary layers.

Wind and boundary layers in Rayleigh-Benard convection. Part 2: boundary layer character and scaling [PDF]

, 1997
The effect of the wind of Rayleigh-Benard convection on the boundary layers is studied by direct numerical simulation of an L/H=4 aspect-ratio domain with periodic side boundary conditions for Ra={10^5, 10^6, 10^7} and Pr=1.

Quantifying non-equilibrium pressure-gradient turbulent boundary layers through a symmetry-based framework

AIP Advances
This study establishes a symmetry-based framework to quantify non-equilibrium processes in complex pressure-gradient (PG) turbulent boundary layers (TBLs), using a Lie-group-informed dilation-symmetry-breaking formalism.

On optical imaging through aircraft turbulent boundary layers [PDF]

, 1980
Optical resolution quality as affected by aircraft turbulent boundary layers is analyzed. Wind-tunnel data was analyzed to obtained the variation of boundary layer turbulence scale length and mass density rms fluctuations with Mach number.

Analytical Model of the Time Developing Turbulent Boundary Layer

, 2007
We present an analytical model for the time-developing turbulent boundary layer (TD-TBL) over a flat plate. The model provides explicit formulae for the temporal behavior of the wall-shear stress and both the temporal and spatial distributions of the ...

Turbulent boundary layer development over an air cavity

Flow
The turbulent boundary layer (TBL) development over an air cavity is experimentally studied using planar particle image velocimetry. The present flow, representative of those typically encountered in ship air lubrication, resembles the geometrical ...
