Combined simulation with real-time force feedback: A new tool for experimental fluid mechanics (Q2724381)

Fluid-structure interaction experiments are very demanding, because they involve complex structural dynamics interacting with turbulent viscous flows.NEWLINENEWLINENEWLINEThe development of a new experimental methodology, wherein direct flow measurements and visualization are conducted in real time and fed back to drive an on-line numerical simulation, has generated new capabilities for the field.NEWLINENEWLINENEWLINEProblems of ensuring closed-loop stability with minimal phase corruption are addressed through two on-going experimental efforts: compliant bluff-body viscous wake interaction employing an active compliance control system, and pressure feedback control of a fish-like laboratory robot, the Robo Tuna.NEWLINENEWLINEFor the entire collection see [Zbl 0961.00036].
