Numerical simulations of synthetic jets in aerodynamic applications
Journal Title: INCAS BULLETIN - Year 2014, Vol 6, Issue 1
Abstract
This paper presents numerical simulations of synthetic jets in aerodynamic applications. We’ve analyzed the formation of isolated synthetic jets, the influence of nozzle geometry and the interaction of synthetic jets with a uniform flow on a flat plate. Also we’ve studied the influence of the active control in interaction with a stalled airfoil and the controllability of dynamic stall phenomenon. The results are obtained using a dedicated CFD solver. Appropriate comparisons are made with results from scientific literature; as well the numerical results are compared with a set of experimental images.
