Chiral dipole in 3d strain flow

This numerical simulation uses the Classical Stokian Dynamics approach. The aggregate with helical windings at the ends starts to roatate in strain flow. We aim to measure its rotation rate around its axis. (This works similar to a stick with two propellers at the endings.) Although the rotation rate is highly dependent on the shape of the used object, it is also linear dependent on the strain rate of the flow. Thus we can use these kinds of particles to measure the strain in turbulent flow. A simular simulation in a different flow with a higher strain rate can be found here:    • Chiral dipole in 2d strain flow   . Simulation was done by Saskia Tympel at TU Eindhoven, Netherlands (http://www.tue.nl/en/university/depar...) in cooperation with the group of Greg Voith in Conneticut, USA (http://gvoth.web.wesleyan.edu/lab.htm).
