Already MEMS are being used commercially in the aerospace and automotive industries for thier small size and weight, and can be mass produced inexpensively using integrated circuit fabrication techniques and micro-machining processes currently available in the industry. In order to investigate if they are suitable for the active contol of fully developed, high Reynolds number turbulent boundary layes, a pilot study of active, open loop, contol of turbulent boundary layers using MEMS is proposed. This experimental invetigation will be carries out with a joint effort by the Uni of Nottingham and Imperial College, with an industrial collaboration of the Sowerby Research Centre of BAe. The ultimate goal would be to obtain a considerable reduction in turbulent skin-friction drag, as suggested in recent DNS studies. Within the lifetime of the proposed project, it is expected that the viability of actuators in controlling the turbulent boundary layers, by suppressing the sweep-like motions through a modification of longitudinal vorticies will be assessed. Prototype micro-fabricated sensors will also be examined for their suitability. An array of skin-friction guages will then be used tio design a heuristic, yet working algorithm to control the turbulent boundary layer.
