  11. MotivationMethod Sierpinski Inertial Upper bound N is independent of ellipse orientation in the disk of this lie in the ellipse

  12. MotivationMethod Sierpinski Inertial explain sier generalizations

  13. MotivationMethod Sierpinski Inertial

  14. MotivationMethod Sierpinski Inertial Inertial particles move in an incompressible fluid (velocity field u) under a synthetic turbulent velocity field Particles, and hence the flow and distribution of them, is characterised by η [0:1]

  15. MotivationMethod Sierpinski Inertial η=0.9
