Theory of microdroplet and microbubble deformation by Gaussian laser beam
Simen Å Ellingsen
The theory for linear deformations of fluid microparticles in a laser beam of Gaussian profile is presented, when the beam focus is at the particle center as in optical trapping. T…
Mixing layer between two co-current Taylor-Couette flows
Simen Å. Ellingsen, Helge I. Andersson
A new mixing layer can be generated if the rotation of either of the two cylinders in a Taylor--Couette apparatus varies discontinuously along the symmetry axis. The mixing zone be…
A bilateral shear layer between two parallel Couette flows
Vagesh D. Narasimhamurthy, Simen Å. Ellingsen, Helge I. Andersson
We consider a shear layer of a kind not previously studied to our knowledge. Contrary to the classical free shear layer, the width of the shear zone does not vary in the streamwise…
