Large Scale Tests on Buoyancy-Driven Vertical Piling Breakwater with Buoyancy-Driven Piles

Buoyancy-driven crack propagation: the limit of large fracture toughness

Energy spectrum of buoyancy-driven turbulence.

Using high-resolution direct numerical simulation and arguments based on the kinetic energy flux Π(u), we demonstrate that, for stably stratified flows, the kinetic energy spectrum E(u)(k)∼k(-11/5), the potential energy spectrum E(θ)(k)∼k(-7/5), and Π(u)(k)∼k(-4/5) are consistent with the Bolgiano-Obukhov scaling. This scaling arises due to the conversion of kinetic energy to the potential ener...

Response Characteristics of a Buoyancy-Driven Sea

The authors consider the flow in a semienclosed sea, or basin, subjected to a destabilizing surface buoyancy flux and separated from a large adjoining reservoir by a sill. A series of numerical experiments were conducted to quantify the energetics of the flow within the basin, that is, the amount of kinetic and potential energy stored within the basin and the rate at which these quantities are ...

The Stability of Buoyancy-driven Coastal Currents

Griffiths, R.W. and Linden, P.F., 1981. The stabil i ty of buoyancy-dr iven coastal currents. Dyn. Atmos . Oceans, 5: 281--306. Buoyancy-dr iven boundary currents were generated in the labora tory by releasing buoyan t fluid f rom a source adjacent to a vertical boundary in a rota t ing container . The boundary removed the Coriolis force parallel to it, a l lowing the buoyan t fluid to spread i...

Galactic dynamos driven by magnetic buoyancy

We consider a mean field dynamo model for the generation of galactic magnetic fields, in which the driving mechanism for the alpha-effect is the buoyancy-driven Parker instability, rather than the conventional cyclonic turbulence. The dominant quenching mechanism is a buoyant velocity, which lifts field away from the disc plane. Our modified alpha-effect is essentially nonlinear, as its magnitu...
