These devices are generated by a piezoelectric diaphragm embedded in a cavity, through an orifice, in a periodic manner. Also, they have the benefit of being compact with zero net mass flux. To study the synthetic jets experimentally, many practical devices can be used, such as artificial excitation, micro valves, pneumatic, etc. Analytically, several approaches were previously used, such as the theory of plate deformation, a lumped element model based on electroacoustic theory, periodic inlet velocity profiles, etc. In the present study, a numerical approach based on a moving mesh method is proposed in the modeling field as a new approach. The mesh deformation is an important approach component for solving problems with moving boundaries or deformable bodies. The motion might be imposed or an implicit part of a coupled fluid-structure simulation. The new model was compared to theory of plates deformation approach, which has previously been used, and both are validated by the experimental data (given in a NASA workshop on Synthetic Jets Validation CFDVAL2004) to evaluate the performed one. Results show that the flow behavior is reproduced correctly by the new approach. %8 2018-04-02
