Optimization Of Wind Fence Enclosures For Infrasonic Wind Noise Reduction
… at its center, and by decorrelating and area averaging the pressure fluctuations at its surface. The optimum wind fence has a surface porosity of 40-55%, a porous roof, no bottom gap, is very tall, wide, and is supplemented by a secondary wind barrier. The optimum wind fence can achieve a …

Resolving Terrain Effects in Borehole Temperature Profiles
… variation of borehole profiles in the regional area of North Dakota, South Dakota, and Nebraska was conducted. Numerous borehole profiles show variation within a given area. Averaging terrain-influenced borehole profiles with undisturbed profiles will affects results. The magnitude of effect is …

Implementation of drop-based oil flow interferometry to estimate wall shear stress in three-dimensional flows
… to thinning oil films are then analyzed with an area-averaging technique, providing a more comprehensive use of the interferogram data to compute wall shear stress. Experiments at Reynolds numbers of 250,000 and 650,000 are performed in the Virginia Tech's Stability Wind Tunnel. The method is …

Excitation of Acoustic Surface Waves by Turbulence
… flow over a flat plate and indicated to an area averaging phenomenon. A wall normal two-dimensional particle image velocimetry (2D-PIV) measurement was performed over the Kevlar covered cavity and a smooth surface to study the effects of the cavity on the flow. The field of view was the same …

Evaluation of the Degradation of Methylene Blue Using Photocatalytic Materials
… a high porosity of 88%, with a specific surface area averaging 150 m²/g. Photocatalytic capabilities are further enhanced as the resultant structure fixes the photocatalyst within the translucent matrix. SGM is capable of photocatalysis combined with diffusion of nucleophiles, electrophiles, and …

Non-Equilibrium Thermodynamics of porous media filled by a fluid flow and of rigid bodies with an internal tensorial field influencing the thermal phenomena.
… structure and coming from the use of volume and area averaging procedures. Understanding the influence of porous tubes on mechanical and transport properties in miniaturized systems is an interesting topic because by experimental and theoretical studies it was found that the porous density has a …

Analysis of the spatial heterogeneity of land surface parameters and energy flux densities
… investigations were carried out for two target areas in Germany. First, satellite data for the years 2002 and 2003 were analysed and validated from the LITFASS-area (Lindenberg Inhomogeneous Terrain - Fluxes between Atmosphere and Surface: a longterm Study). Second, the data from the …
