A sphere in a uniformly rotating or shearing flow

JJ Bluemink, D Lohse, A Prosperetti… - Journal of fluid …, 2008 - cambridge.org
It is known that, in a linear shear flow, fluid inertia causes a particle to spin more slowly than
the surrounding fluid. The present experiments performed with a sphere with fixed centre …

Numerical analysis of the angular motion of a neutrally buoyant spheroid in shear flow at small Reynolds numbers

T Rosén, J Einarsson, A Nordmark, CK Aidun… - Physical Review E, 2015 - APS
We numerically analyze the rotation of a neutrally buoyant spheroid in a shear flow at small
