Multiobjective optimal control of fluid mixing

In this contribution an efficient numerical method to solve multiobjective optimal control problems of fluid flow mixing governed by the advection equation is presented. To obtain well-mixed behavior for non-diffusive processes, the multi-scale mixing of measure introduced in [1] is used in the formulation of the multiobjective optimal control problem. For the approximation of the Pareto set we combine reference point methods with an adjoint based optimization approach. (© 2015 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)
