| 摘 要： | 为了更深入地研究合成喷射流性能与激励器结构参数的关系,在考虑气体可压缩性质的条件下,对合成喷射流进行了理论分析,得出了合成喷射流性能与激励器结构参数的函数关系式,并采用动边界条件模拟实际压电膜的振动,对合成喷外部射流场和激励器腔体内部射流场进行了联合数值模拟.计算结果与已有的实验结果及理论分析结果吻合较好,验证了该数值模拟方法的可行性.

| Abstract: | Synthetic jet flow is created by the compression effect in actuator's cavity caused by vibration of piezoelectric diaphragm,whose mechanism is similar to a micro compressor.To get the relationship between the performance of synthetic jet flow and the actuator parameters,the compressibility of gas has been considered and the correlation function reflecting that relationship was obtained by theoretical analysis.The vibration of piezoelectric diaphragm was simulated using moving boundary condition and numerica... |
