Abstract: We focus on the enhancement of mixing in a mixing layer using a combination of adjoint based optimization and DNS. The mixing of momentum in a temporal mixing layer is
considered, where small initial perturbations on the mean velocity field are optimized to reach a well-mixed turbulent state at the end of the simulation time window. Optimization cases are presented for 6 different optimization time horizons. Based on this, the sensitivity
of the mixing-layer flow properties to the initial controls is investigated, including the behavior for long time windows, for which the optimized layer seems to converge to a self-similar state much faster than usually reported in literature.
