The Heads and Tails of Buoyant Autocatalytic Balls
Michael C. Rogers, Stephen W. Morris
Buoyancy produced by autocatalytic reaction fronts can produce fluid flows that advect the front position, giving rise to interesting feedback between chemical and hydrodynamic eff…
Autocatalytic plume pinch-off
Michael C. Rogers, Abdel Zebib, Stephen W. Morris
A localized source of buoyancy flux in a non-reactive fluid medium creates a plume. The flux can be provided by either heat, a compositional difference between the fluid comprising…
Natural versus forced convection in laminar starting plumes
Michael C. Rogers, Stephen W. Morris
A starting plume or jet has a well-defined, evolving head that is driven through the surrounding quiescent fluid by a localized flux of either buoyancy or momentum, or both. We stu…
The meandering instability of a viscous thread
Stephen W. Morris, Jonathan H. P. Dawes, Neil M. Ribe +1
A viscous thread falling from a nozzle onto a surface exhibits the famous rope-coiling effect, in which the thread buckles to form loops. If the surface is replaced by a belt movin…
Parametric internal waves in a compressible fluid
Kausik S. Das, Stephen W. Morris, A. Bhattacharyay
We describe the effect of vibration on a confined volume of fluid which is density stratified due to its compressibility. We show that internal gravity-acoustic waves can be parame…
Autocatalytic chemical smoke rings
Michael C. Rogers, Stephen W. Morris
Buoyant plumes, evolving free of boundary constraints, may develop well-defined mushroom shaped heads. In normal plumes, overturning flow in the head entrains less buoyant fluid fr…
