This paper presents development of numerical model of plasma synthetic jet actuator (PSJA) used to active flow control. Proposed Eulerian-Lagrangian model, named pseudo-viscosity particle model computing effect of PSJA is applied to 3-dimensional flow around a NACA 0012 airfoil with single PSJA and is compared its result with another numerical model, namely, synthetic jet model and experimental data. Using our model, PSJA have an influence on apparent viscosity, that is, it reduce turbulent eddy viscosity calculated by Large Eddy Simulation (LES) and is traced by Lagrangian particles. For the case of angle of attack are 0 and 7 degress, results using our model agreed with experimental profile on wake qualitatively but synthetic jet model didn't.
