Visualization of scalar velocity fields over one- and two-dimensional structures
Visualization techniques for representing scalar velocity fields over one- and two dimensional vibrating structures are investigated. High spatial density velocity fields are measured over a vibrating beam and a vibrating plate by a scanning laser velocimeter. The velocity measurements are assumed …

Combined tangential-normal injection into a supersonic flow
… slot heights downstream from which Mach number, density, velocity and entrainment rates were calculated. Various dimensions and spreading angles of the mixing regions were measured directly from Nanoshadowgraphs and Schlieren photographs. Large eddy structures were produced in several cases, …

Improving shock-capturing robustness for higher-order finite element solvers
… variables based on the primitive variables (density, velocity, and temperature) are developed to allow the convergence of solutions with nonphysical oscillations. The surrogate variables are applied to a flow with a strong shock feature, with and without continuation methods, to demonstrate …

Turbulence measurements of heated supersonic slot injection into a supersonic stream
… K. The effects on the flow of these changes in density, velocity and temperature was investigated. Measured quantities included the mean and rms levels of the mass flux and total temperature. Nanosecond Shadowgraphs and spark Schlieren photographs were taken. The Favre-averaged velocity …

Simulations of dark energy cosmologies
… space power spectrum, including the non-linear velocity divergence power spectrum, is presented. We have found a density-velocity relation which is cosmology independent and which relates the non-linear velocity divergence spectrum to the non-linear matter power spectrum. We provide a formula …

Vortices of the Mozambique ridge current
… characteristics (i.e. temperature, salinity, density, velocity, volume transport, energy) and distribution of such vortices? How and where are the vortices generated, and what are their lifetime and eventual fate? In all, more than 500 routine hydrographic stations were occupied to collect …

Molecular Dynamics Study of Solid-Liquid Heat Transfer and Passive Liquid Flow
… and liquid, local pressure, surface tension, density, temperature calculation methods, realistic boundary conditions, etc. Heat transfer between solid and fluids has been a challenging area in MD simulations, and has only been minimally explored (especially for a practical fluid like water). …

Effects of Exercise and Traditional Chinese Medical Modalities on Bone Structure and Function
… (BUA), a measure of bone structure and density, velocity of sound (VOS), an indicater of the elastic modulus and the breaking forces of bone as provided by ultrasound parameters, were evaluated. The levels of osteocalcin (OSTN) in serum, a biomarker of bone formation and the levels of …
