✦ Synopsis

In the present paper suboptimal boundary control strategies for the time-dependent, incompressible flow over the backward-facing step are considered. The objective consists in the reduction of the recirculation bubble of the flow behind the step. Several cost functionals are suggested and a frame for the derivation of the optimality systems for a general class of cost functionals is presented. Numerical examples are given.

Recirculating flow around a backward-facing step is caIculated by large eddy simulation (LES). The reattachment length is found to be xR/H = 8 for a Smagorinsky constant of C = 0.15, and xR/H = 9 for C = 0.10. In the recirculating region, three eddy structures can be observed in the instantaneous st
