Bubbly but quiet

Live with a Quiet but Uneasy Status Quo?

Whether a trade ban on a product imposed because of the fact that the process-and-production-method (PPM) of that product is harmful to the environment can be consistent with the WTO law? The purpose of this paper is to trace what the panels and the Appellate Body of the WTO have done in settlement of disputes concerning this problem and especially to think about a possible ‘evolutionary’ role ...

Understanding Bubbly Episodes

Lift force in bubbly suspensions

Closure relations are presented for the lift coe.cient for ordered arrays of 2-D and 3-D bubbles at various bubble volume fractions. These were determined via lattice Boltzmann simulations of bubble rise in periodic boxes, where the bubbles were also subjected to shear. The single-bubble lift coe.cient, determined by low-shear computational experiments, varies in a systematic manner with the as...

Evolving Solitons in Bubbly Flows

At the end of the sixties, it was shown that pressure waves in a bubbly liquid obey the KdV equation, the nonlinear term coming from convective acceleration and the dispersive term from volume oscillations of the bubbles. For a variable u, proportional to -p , where p denotes pressure, the appropriate KdV equation can be casted in the form ut 6uu~ + u ~ = 0. The theory of this equation predicts...
