Abstract
The present study considers the development of a Laminar Separation Bubble on the suction side of a NACA0018 airfoil under natural and forced conditions. Deterministic forcing is applied by means of a two-dimensional plasma actuator installed on the airfoil surface. The spatiotemporal characteristics of the bubble are measured using time-resolved, two-component Particle Image Velocimetry in streamwise and spanwise planes. Analysis of the results shows that while the time-average bubble is strongly two-dimensional, the dominant coherent structures assume three dimensional organisation in the vicinity of laminarturbulent breakdown in both natural and forced conditions.
