Abstract

This paper deals with identification of dynamics in suction control of airfoils for low Reynolds number regimes (8 × 104 - -5 × 105). In particular, the dynamics of interest is the map that relates suction pressure and surface pressure. Identification of such dynamics is of use to a variety of active control applications including suction control in small/medium wind turbines which operate in these Reynolds number regimes. Prior research has largely focussed on higher Reynolds number regimes, creating a need for such a study. The dynamic relation between suction and surface pressure was identified as an overdamped second order system. Copyright © 2013 by ASME.
