Abstract:

Flow control may be achieved by using MEMS to alter the fine scale flow structures within a boundary layer. We here report on a detailed direct numerical simulation of slot jet MEMS for the purpose of flow control. Individual pulses were aimed at specific boundary layer structures, or were created in a flow combed by riblets. A feedback control method is also studied and used to calibrate the strength of actuation to match flow conditions. This final report, on a one-year project funded between two longer term related projects, describes a few conclusive findings as well as work in progress.
