Synthetic jet pump is a potential technique to improve the pumping performance by introducing a smart structure which can enhance counter-rotating vortexes. Aligning with this approach, a new structure of valveless micro-pump is developed in this work. The mechanism of the present micro-pump is based on the combination of the nozzle and a tesla element to rectify the synthetic jet. The new structure of “ace of spades” nozzle, named Tesla coupled nozzle, creates series of vortexes at the orifice of the pump chamber that allows to attenuate the reversed flows while fluid is drawn through the pump. The present micro-pump is simple but robust and can perform at rather low voltages.

合成射流泵是一种潜在的技术，它通过引入可以增强反向旋转涡流的智能结构来提高泵送性能。与这种方法相一致，这项工作开发了一种新的无阀微型泵结构。本微型泵的机理是基于喷嘴和特斯拉元件的组合来校正合成射流。名为“黑桃王牌”喷嘴的新结构（称为特斯拉耦合喷嘴）在泵腔的孔口处形成一系列涡流，当流体通过泵吸入时，该涡流可减弱反向流动。本微型泵简单但坚固，可以在相当低的电压下运行。
