摘要

摘要: 低噪声、低消耗、高推进效率是新一代仿生水下推进技术的主要研究方向。基于生物仿生机理, 文中提出了一种利用介电弹性体(DE)的电致变形驱动合成射流驱动器设计方法, 并对其在工作过程中的流场进行了有限元仿真。仿真结果表明, 该合成射流驱动器产生的流体喷射具有合成射流的特征, 能够形成一系列的涡环, 射流在涡环的卷吸作用下保持了较好的方向性。文中研究结果在新一代仿生合成射流驱动领域具有很好的应用前景。

Abstract: Based on the biomimetic mechanism, a design method of synthetic jet actuator actuated by dielectric elastomer (DE) electro-deformation is proposed, and finite element simulation of the flow field in its working process is carried out. The results show that the fluid jet produced by the synthetic jet actuator has the characteristics of synthetic jet, which can form a series of vortex rings, and the jet maintains good directivity under the entrainment effect of the vortex ring. This design may have good application prospect to new generation of biomimetic synthetic jet actuating.
