  author={Alexander Vikhansky},
In this study we consider a method for enhancement of mixing in time-periodic laminar flows. The stretching rate along unstable manifold of the chaotic flow is considered as a quantitative criterion of mixing quality. Optimal control theory is applied for improving the stretching rate in a prototypic cavity flow. It is demonstrated that the optimal flow field tends to stretch the infinitesimally small vectors that are distributed along the material interface. The higher is the length of a… CONTINUE READING
