摘要
为增强燃气/氧气的掺混,基于旋涡系统的非线性控制理论,在合成射流激励器的简化模型基础上,对激励器组处于不同工作情形下增强燃气/氧气的掺混流场进行了数值模拟和分析比较,结果表明:合适的激励器工作组可以显著增强燃气/氧气的掺混程度及换热,合成射流的控制效果与激励器的布局、强度和相位等密切相关。
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 appropriate synthetic jet actuators workgroup can significantly enhance fuel/oxygen mixing.
