Emergent order in rheoscopic swirls
Michael Wilkinson, Vlad Bezuglyy, Bernhard Mehlig
We discuss the reflection of light by a rheoscopic fluid (a suspension of microscopic rod-like crystals) in a steady two-dimensional flow. This is determined by an order parameter…
Poincare Indices of Rheoscopic Visualisations
Vlad Bezuglyy, Bernhard Mehlig, Michael Wilkinson
Suspensions of small anisotropic particles, termed 'rheoscopic fluids', are used for flow visualisation. By illuminating the fluid with light of three different colours, it is poss…
Multiple regimes of diffusion
B. Mehlig, M. Wilkinson, V. Bezuglyy +2
We consider the diffusion of independent particles experiencing random accelerations by a space- and time-dependent force as well as viscous damping. This model can exhibit several…
