Tracking areas with increased likelihood of surface particle aggregation in the Gulf of Finland: A first look at persistent Lagrangian Coherent Structures (LCS)
We explore the possibility to identify areas of intense patch formation from floating items due
to systematic convergence of surface velocity fields by means of a visual comparison of …

Multifractality of fine bubbles in turbulence due to lift
We develop a theory of spatial distribution of fine bubbles in turbulence and confirm it
numerically. The bubbles are a few hundred microns in size and the considered value of the …

Sticky particles in compressible flows: aggregation and Richardson's law
J Kalda - Physical review letters, 2007 - APS
The evolution of the distance r (t) between a pair of passive tracer particles in rough
compressible velocity fields is studied. The scaling behavior depends on the stickiness of …

Generation of large pollution patches via collisions of sticky floating parcels driven by wind and surface currents
We study the evolution of large systems of sticky patches of pollution that float on the sea
surface and are moved around by realistic wind and simulated surface currents. The study …
