A Numerical Simulation has been conducted to investigate the mixing of coaxial jets with zero-mass-flux synthetic jet actuators, two arrays of which are placed side by side around coaxial jets and in the exit plane of the outer primary jet. Both the temperature field of the primary jet and mixing processes are studied at given temperature ratio. High-frequency forcing leads to increases in the radial extent of the jet and turbulent intensity in the near-field and increased turbulent dissipation. During the analysis, the influence of adjacent synthetic jets is also considered. The comparison is made between the control effectiveness of two arrays of actuators and that of an array of actuators. The results show both of the actuator’s configurations can result in the significant mixing enhancement, but the former exhibits more desirable.
