| Abstract: |
| Based on non-linear control theory of the vortex system, the operation principle, characteristics and potential applications of the synthetic jet technology were introduced briefly. To enhance the fuel/oxygen mixing, simplify the model of synthetic jet actuator, the flow-field of mixing enhancement using synthetic jet actuators at different cases was simulated. It is shown that an appro-priate synthetic jet actuators workgroup can significantly enhance fuel/oxygen mixing. |
