Fast optimal control of asymmetric flow field flow fractionation processes

We present optimization problem for Asymmetric Flow Field Flow Fractionation, which is a widely used technique for segregation of two or more particles of submicron scale, according to their hydrodynamic radius. We give a short description of AF4 and present one way coupled model. For an optimization problem we use the sensitivities due to the special structure of the objective functional for this specific application and memory constraints.
