- Abstract
- Curretly, the development of MEMS(Micro Electronic Mechanical System) technology awakes
many research's interest for the aerodynamics. This work presents the development of a compact
synthetic jet actuator for flow separation control at the flat plate. The formation and evolution of
fluidic actuators based on synthetic jet technology are investigated using Reynolds-Averaged
Navier-Stokes equations. Also, 2-Dimensional, unsteady, incompressible Navier-Stokes equation
solver with single partitioning method for Multi-Block grid to analyze and a modeled boundary
condition in developed for the synthetic jet actuator. Both laminar and turbulent jets are
investigated. Results show very good agreement with experimental measurements. A jet flow
develops, even though no net mass flow is introduced. Pair of counter-rotating vortices are observed
near the jet exit as are observed in the experiments.
