boundary layer growth and hence displacement thickness are the key factors in shock position over aerodynamical surfaces at transonic regimes. since boundary layer growth is a function of free stream reynolds number and also of the transition location, the free stream reynolds number and also the other parameters involved in the boundary layer growth and its transition location are determinant ...

Phase-averaged organized oscillation velocities (U,V,W) and random fluctuation Reynolds stresses ( uw , uv , ww , vv , uu ) are presented for the nominal wake of a surface ship advancing in regular head (incident) waves, but restrained from body motions, i.e., the forward-speed diffraction problem. A 3 × 3 × 100 m towing tank, plunger wave maker, and towed, 2D particle-image velocimetry (PIV) a...

Tangential and normal velocity profiles of the boundary layer surrounding live swimming fish were determined by digital particle tracking velocimetry, DPTV. Two species were examined: the scup Stenotomus chrysops, a carangiform swimmer, and the smooth dogfish Mustelus canis, an anguilliform swimmer. Measurements were taken at several locations over the surfaces of the fish and throughout comple...

Love-type wave generation in a fiber-reinforced medium placed over an inhomogeneous orthotropic half-space is analysed. The upper and lower boundary surfaces of the fiber reinforced medium are periodically corrugated. Inhomogeneity of half-space is caused by variable density and variable shear modules. Displacement components for layer and half-space are derived by applying separable variable t...

Dimethylsulfide (DMS, CH3SCH3) produced by phytoplankton degredation is thought to be the major source of the sulfate and methanesulfonate aerosol found in the marine boundary layer. An understanding of the mechanism of formation of these aerosols is critical in evaluating the factors which control visibility in the marine boundary layer. The primary objective of this research effort is to dete...

in this paper, the accuracy of k- and k- turbulence models in super sonic boundary layer capturing of smooth/rough flat plates have been comprehensively investigated. among these investigations, some sorts of sensitivity analysis, including change in turbulence model, generated-grid density, near wall affects, c magnitude (for boundary layers generated on smooth flat plates), and change in c...

In FY14, the objectives of our analyses of the WP-3D based LASP measurements are to understand: 1) marine atmospheric boundary layer (MABL) structure and characteristics during the DYANMO/LASP field campaign; 2) influence of convection on MABL structure and the variability of atmospheric boundary layer thermodynamic properties across the DYNAMO domain during the suppressed and active phase of M...

Solitary electrostatic structures have been observed in and around auroral zone field lines at various altitudes ranging from close to the ionosphere, to the magnetopause low-latitude boundary layer (LLBL) and cusp on the dayside, and to the plasma sheet boundary layer on the nightside. In this review, various models based on solitons/double layers and BGK modes or phase space holes are discuss...
