Scaling laws for jets of single cavitation bubbles

Mohamed Farhat, Nicolas Dorsaz, Danail Obreschkow, Philipp Kobel, Outi Supponen, Marc Tinguely

Fast liquid jets, called micro-jets, are produced within cavitation bubbles experiencing an aspherical collapse. Here we review micro-jets of different origins, scales and appearances, and propose a unified framework to describe their dynamics by using an ...

Bed shear stress estimation for gravity currents performed in laboratory

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Jessica Zordan

Gravity currents are caused by density differences between two fluids which may be due to temperature, dissolved substances or the presence of particles in suspension. In this study saline currents, in which the higher density is produced by dissolved salt ...

Time evolving bed shear stress due the passage of gravity currents estimated with ADVP velocity measurements

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Jessica Zordan

Instantaneous longitudinal velocity fields are derived from the velocity measurements collected with the ADVP. Detailed velocity profiles are the base for the estimation of the bottom shear stress through the logarithmic law of the wall. Bottom shear stres ...

Effect of gravity framing on the overstrength and collapse capacity of steel frame buildings with perimeter special moment frames

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

This paper investigates the effect of the gravity framing system on the overstrength and collapse risk of steel frame buildings with perimeter special moment frames (SMFs) designed in North America. A nonlinear analytical model that simulates the pinched h ...

(Re-)inventing the relativistic wheel: gravity, cosets, and spinning objects

Alexander Monin, Francesco Riva, Solomon G Shamsuddin Osman Endlich

Space-time symmetries are a crucial ingredient of any theoretical model in physics. Unlike internal symmetries, which may or may not be gauged and/or spontaneously broken, space-time symmetries do not admit any ambiguity: they are gauged by gravity, and an ...

Visualization of the internal flow properties and the material exchange interface in an entraining viscous Newtonian gravity current

Christophe Ancey, Belinda Margaret Bates

In order to simulate a simple entraining geophysical flow, a viscous Newtonian gravity current is released from a reservoir by a dam-break and flows along a rigid horizontal bed until it meets a layer of entrainable material of finite depth, identical to t ...

The quest for the most spherical bubble: experimental setup and data overview

Mohamed Farhat, Nicolas Dorsaz, Danail Obreschkow, Philipp Kobel, Aurèle De Bosset, Marc Tinguely

We describe a recently realized experiment producing the most spherical cavitation bubbles today. The bubbles grow inside a liquid from a point plasma generated by a nanosecond laser pulse. Unlike in previous studies, the laser is focussed by a parabolic m ...

Phase Analysis of the Stretching Cycles of the Head of Unsteady Gravity Currents Developing over Smooth and Rough Beds

Mário Jorge Rodrigues Pereira Da Franca, Helena Isabel Dos Santos Nogueira, Claudia Adduce

Gravity currents are buoyancy driven flows occurring spontaneously in nature or resulting from human intervention. Examples of gravity currents in the water are oceanic fronts, resulting from differences in temperature and salinity, and turbidity currents ...
