Software examples

Time-periodic sine flow

This example provides all scripts to create the matrices, but also to study the effect of T on mixing.

Details are available in M.K. Singh, M.F.M. Speetjens, P.D. Anderson, Eigenmode analysis of scalar transport in distributive mixing, Phys. Fluids, 21, 093601, (2009)

Below a number of tools are downloadable to analyse prototype mixing flows. Matlab is needed to run these examples, where in some cases precomputed mapping matrices are prvodided, while in other cases, like the time-periodic sine flow, also the option is made for the user to build matrices.

Lid-driven cavity

The lid-driven cavity flow is one of the classical examples of simple flows that may lead to chaotic advection. This relatively simple script makes it possbile to move top and bottoms walls. The intensity of segragation is computed on the fly.

Journal bearing

This example gives the user almost complete freedom to create an initial input for the concentration distribution.

Details are available in O.S. Galaktionov, P.D. Anderson, G.W.M. Peters, Structure development during chaotic mixing in the journal bearing flow, Phys. Fluids, 14(9), 3009-3017, (2002)

Kenics statics mixer
