Simulation of bubble expansion and collapse in the vicinity of a free surface

The present paper focuses on the numerical simulation of the interaction of laser-generated bubbles with a free surface, including comparison of the results with instances from high-speed videos of the experiment. The Volume Of Fluid method was employed fo ...

Practical mapping of the draw resonance instability in film casting of Newtonian fluids

Mathias Simon Daniel Bechert

The influence of viscosity and inlet velocity on the draw resonance instability of film casting processes is quantitatively analysed. By linear stability analysis of a Newtonian model including inertia and gravity effects, stability curves for different co ...

The Tenth Data Release Of The Sloan Digital Sky Survey: First Spectroscopic Data From The Sdss-Iii Apache Point Observatory Galactic Evolution Experiment

Jean-Paul Richard Kneib, Zheng Zheng, Johan Comparat, David Schlegel, Timothée Guy Olivier Delubac, Ginevra Favole, Yue Shen, Arnaud Borde, Bo Ma

The Sloan Digital Sky Survey (SDSS) has been in operation since 2000 April. This paper presents the Tenth Public Data Release (DR10) from its current incarnation, SDSS-III. This data release includes the first spectroscopic data from the Apache Point Obser ...

The effect of pressure gradient on the collapse of cavitation bubbles in normal and reduced gravity

Marc Tinguely

When water flows through hydraulic turbomachines, the local pressure can become low enough to vaporize the water and create vapor cavities. This phenomenon is called cavitation. When the cavities collapse, shock waves and liquid jets traveling through the ...

A Simple Model for the Afternoon and Early Evening Decay of Convective Turbulence Over Different Land Surfaces

Marc Parlange, Chad Higgins, Eric Richard Pardyjak, Daniel Nadeau

A simple model to study the decay of turbulent kinetic energy (TKE) in the convective surface layer is presented. In this model, the TKE is dependent upon two terms, the turbulent dissipation rate and the surface buoyancy fluctuations. The time evolution o ...

Alternative depth-averaged models for gravity currents and free shear flows

Anton Schleiss

Two approaches have traditionally been used to describe the widening rate of jets and plumes: the diffusion concept of Prandtl, and the entrainment principle of Morton, Taylor and Turner. The entrainment concept is based on depth-averaged flow scales, and ...

Flow field investigation in a rectangular shallow reservoir using UVP, LSPIV and numerical modelling

Anton Schleiss, Giovanni De Cesare, Sameh Ahmad Kantoush

Low velocity and shallow-depth flow fields often are a challenge to most velocity measuring instruments. In the framework of a research project on reservoir sedimentation, the influence of the reservoir geometry on sediment transport and deposition was stu ...

Kilohertz quasi-periodic oscillation and atoll source states in 4U 0614+09

Demetri Psaltis

We report three RXTE/PCA observations of the low-mass X-ray binary 4U 0614+09. They show strong (similar to 30% rms) band-limited noise with a cutoff frequency varying between 0.7 and 15 Hz in correlation with the X-ray flux, f(x). We observe two nonsimult ...
